If you create two new fields in your feature table make the double precision fields.  One for X one for Y. In an edit session right click on the X field and choose calculate geometry.  From the drop down menu choose X coordinate of centroid.  Then do the same for Y I would like to calculate the centroid (x and y co-ordinate) of a polygon using model builder - ArcGIS 10.1 Standard. I don't have access to the tool Feature to Point as the standard licence doesn't allow this option and there doesn't seem to be a Calculate Geometry tool within model builder. Can anyone help please ... View more

What are you trying to change the color on? I think it would me the most simple to simply add an air photo background. if you click on the drop down arrow on the add data button.. Yellow Triangle with a Plus sign.  Go to Add Basemap and you will see the option to add air photography. If you add your buildings or some other part of your map first it will add the air photography as a back ground. Thanks for your comment robert, but i dont understand what you mean about air photo? only dem or terain data, or maybe air foto like lidar or other ortho image, i already have data building (polygon), sidewalk (polygon), landuse (polygon), road (polyline and polygon) dem and quickbird image, i realy confused how make the colour i mean the green colour which have a tree or vegetation in side. can you explain to me robert how make that? is it use cartography representation? ...

Try adding the polygon by itself in a session.  Does it add. Now add a landbase feature such as roads.  Does the road appear in the proper location in reference to the polygon? I am trying to upload a polygon file showing communities in Texas, but keep receiving the following message from Community Analyst: "This location is not in the country you selected and can't be used for analysis and reports. Change your country selection above and try again." The country is set to USA. The data has been projected in NAD_1983_StatePlane_Texas_South_FIPS_4205_Feet. I have tried reprojecting and reuploading the data but keep getting the same message. Any ideas would be greatly appreciated! ... View more

The data can sort either alpabetically or numerically.  If you have numbers in your sort and letters it will sort alphabetically so your numbers will not sort properly. If you want to keep them in order when you split your best practice may be to start at the digitized beginning and split it while going down the line. I'm having a bit of trouble sorting a polyline feature class in the correct order. Basically I have a polyline feature calss with multiple features in it that form a single line. This feature class was produced by taking a single polyline and splitting it at specified points (using the Split at Point tool). The resulting feature class has multiple polyline features in a somewhat random order. What I need to do is re-order these feature classes from a start point at one end of the line to the end of the line. I have tried the Sort tool and that works some of the time, but not all of the time as occasionally the original line winds and turns a lot and that seems to mess up the Sort tool. Does anyone know of a simple way or tool to do this without having to get into any crazy Python scripting that manipulates the geometry? This seems like a fairly logical need, so I'm hoping there is a simple way to do it. Thanks, ... View more

How are you performing the clip. the easy way is to select your polygon and then from the editor toolbar select the editor drop down tab and choose clip Did you ever figure out a solution to this? I am getting the same error (ERROR 000438: Overlay not a Polygon) when I try clipping. One shapefile is a line geometry type and the other is a polygon geometry type. I tried the above solution, exporting the data and saving to a different folder, and new document. I am still getting the same error every time. Thanks. ... View more

Go to your layout view.  right click somewhere that is not a map element.  Select ArcMap Options. Click on the layout view tab.  There a window section for Snap Elements to: Hello, I have a bunch of small picture elements in data view that I'm trying to arrange, and they keep snapping to something (grid? I have no idea what) and I can't place them where I want to. Snapping is off (but this isn't in an edit session anyway) and all 'snap elements to..' are unchecked in the layout options (though I'm not doing this in layout view). I've tried holding down shift/ctrl/alt/ etc. while dragging, this doesn't work. Is there a way to stop this behavior? Thanks! ... View more

You may be able to create it quick and easy using online geocoding services. You should have a table that contains Address City State Zip Zip+4 if available Country the address should not have things like suite or apartment.  that should be an address2 field which you will not use. Start ArcGIS and add the table to the  session. Click on the list by source button so you can see the table. Right click on the table and select GeoCode Addresses. A window will pop up prompting you use select an address locator.  If you have a table like the one I specified select 10.0 North American Geocode Service or North American GeoCode Service.  You can select different ones and a window will pop up prompting you to select which columns have the required data. If you name them as the service looks for them(as I have them above) it should automatically find them. The more data you have the more accurate it will be. One of the drawbacks of geocoding is it is not 100% accurate.  It tends to get close but often will not be dead on.  There are more advanced methods of geocoding but they involve creating accurate center line data that has the address ranges in it.  And the smaller your center lines segments are the more accurate it is. Hi, I need to create xy points to represent certain facilities. The data I have to create these points are the following: Address data for the facilities which includes street address but no lat/long data A polyline file of the road networks. This includes the street name, direction, type, city, and census district info (e.g. code and names) Polygon map of FSAs I am uncertain of how many points I will need to create - it may be hundreds. Can I create these points quickly by using the road network data (if so, how?), or will I have to manually digitize all of my points? Is there a way I can tell ArcGIS to create the points for me along the road network polyline file? Thanks Cecilia ... View more

If you save a feature as a layer file it will save the color scheme based on how you have the colors done up in your symbology. you can import the symbology given that they basis for the color is the same. ... View more

Your over thinking it. Simply make your MXD into the projection you want to use.  When you create a new mxd it should automatically assign the projection to the projection of the first file you add it if has a projection. Hi, I have written a standalone application that will export Shape files but I need some help with the prj files. How can I write custom geodesy to the prj so that my shape files will load in ArcMAP whitout triggering this annoying "Geographic Coordinate Systems Warning" dialogue box? My current prj file looks like this (on one single line of course): PROJCS["MyED50NUTM31N", GEOGCS["MyED50N", DATUM["<custom>", SPHEROID["<custom>",6378388.0,297.0], TOWGS84[-116.641, -56.931, -110.559, 0.893, 0.921, -0.917, -3.52]], PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]], PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",500000.0], PARAMETER["False_Northing",0.0], PARAMETER["Central_Meridian",3.0], PARAMETER["Scale_Factor",0.9996], PARAMETER["Latitude_Of_Origin",0.0], UNIT["Meter",1.0]] Does ArcMAP read the TOWGS84 parameter? (As listed here http://docs.geotools.org/stable/javadocs/org/opengis/referencing/doc-files/WKT.html) When I manually define a custom datum transformation in ArcMAP, the "CreateCustomGeoTransformation" tool will show this syntax: GEOGTRAN(METHOD('Position_Vector'],PARAMETER['X_Axis_Translation',-116.641],PARAMETER......... Can I use this syntax in my WKT (=prj) file instead of the TOWGS84 parameter? I don't want to adopt the ESRI or EPSG naming / numbering scheme. I want full flexibility for custom definitions - it should work even it's not already defined by ESRI or EPSG. Is this possible? PS: I know that particular shift is already predefined in ArcMAP - I'm just using it as an example. BR, Leifster ... View more

this map looks like a combination of an air photo and polygons that represent different features. First create individual feature classes for each type of feature. From what I can see here I would say building, sidewalks and it looks like roads. You can also create a polyline feature for the roads as well to make it easier to label. You open your air  photo first.  Then in an edit session you start to draw in your buildings based on the outline of the buildings in the air photo. Drawing the sidewalks like the image is the same but a little more tricky.  I would draw portions of the sidewalks so you can leave the open areas open then just merge them together when you are done. It also looks like the drew in the roads.  What I do for roads like this is I draw a center line down the middle of the road. I then include a column to designate the width of the road as measured from the center line.  i.e. a 60 foot wide road would measure 30 feel from center.  I then buffer the roads based on the road width field. Looking closer like under the Pauley Pavilion ( they spelled it Pavillion on their map) it looks like they drew some features in with lines.

Are people doing edits on your online service? I keep the master copy of my clients database in a personal SDE and upload data changes to the server when required.  that upload can be automated to run nightly as well. I am a server administrator who is totally new to ArcGIS. I just set up ArcGIS for Server 10.1 SP1 on Windows Server 2008 R2 and am now investigating backup and recovery. There is a section titled "Backing up and restoring your ArcGIS Server site" in ArcGIS Help which basically says that in order to make a backup you need to "delete all machines from your site", taking the site offline, then back up the relevant directories and then run the "create new site" wizard, trying to remember to do it exactly the same way as when you first configured the site. REALLY? This can't be serious. I can't imagine anyone making regular backups of their ArcGIS server using such a disruptive, labour-intensive and error-prone method. Maybe if you have a dedicated ArcGIS server administrator who has no other duties - but how many organizations have such a person? As with all our servers, I configured Tivoli Storage Manager to take nightly backups of the server files. On cursory look, the files in configuration and data directories seem to be there. TSM complained about some files that it couldn't back up because 'the object is in use by another process', but they don't seem very critical to me: C:\Apps\ArcGIS\Server\geronimo\var\txlog\howl_1.log': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\2096': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\2160': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\2408': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\3344': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\3624': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\3772': the object is in use by another process C:\Users\arcgis\AppData\Local\Temp\hsperfdata_arcgis\3996': the object is in use by another process Is such a backup really unusable for recovery? ...

If you only need to do it the one time then simply use a combination of Select by Attributes and Field Caluclator on the table. Select by attributes columnA > columnB and ColumnA > columnC This will give you all the columnA which are larger then both B and C Then from that selection query populate columnD with the Value of ColumnA Then do similar queries for ColumnB and ColumnC Do it three times and you are done. You cold also create this as tool in model builder and save it as a button. Out of the box.  But as I wrote if you only need to do it once or every few months it is just as well to do it with select by attributes and field calculator. Hi, I am wondering if there is a tool that will look at a row, find the maximum value from column A, B, or C and then update column D with the name of the highest-ranked column. I could implement this as a cursor in Python but I would like to know if there is a set-based method that could be performed with ArcGIS Desktop (I have previously done this in SQL Server, but want to keep the requirements to a minimum). At this stage the data is a polygon derived from an intersect, but it could also be modelled as a series of rasters. Thanks, Matt ... View more

From your Contents you need to share it with the group. Hello, I uploaded a shape file to my map.

Create a geodatabase with a feature dataset in the projection you want it to be.  the export your event to that feature dataset. I manually import a CSV to create a table which I use to make an XY event layer during the creat process I can select the coordinate system of my CSV (NAD 27 LL) and the transformation to use for the conversion to the data frame (Web Mercator). I have been reading about the make xy event functionality, but I am missing the transformation part. ... View more

Couple questions. Have you upgraded your Database to 10.1? How large are the  MXD's that you are trying to open? Are you trying to open online sources? Are you using MXD's that were created before 10.1? Do you regularly compress your geodatabase? Are you features in a Geometric Network and or in SDE? In Windows Explorer navigate to your geodatabase.  How large is it? Now in ArcCatalog compress your geodatabase.  Now how large is it?  If it went down dramatically you should see an increase in performance. Open your windows explorer.  Right click on the properties for your hard drive.  How much space do you have left on  your hard drive?  If you have anything less than 10% you have space issues.  Does not really matter how large your hard drive is but what percentage is left is critical.  If you have less than 10% delete or uninstall anything you can then... Run Disk Cleanup on  your hard drives. Run Disk Defragmentor on your hard drives. After compressing your database, running cleanup on your HDD and de-fragmenting your HDD are you still having issues? If your MXD that you are using is very large (over 7mb) you may need to take steps to reduce it. I have been having issues with opening ANY mxd in 10.1. The software itself opens fine, but if I try to open a mxd it takes a long time to load. I have tried deleting the normal.mxt and have tried creating different mxds and trying them, but it seems as though it takes a long time no matter what. It is not 'drawing' while I wait for it to load either, rather it just shows the little blue loading circle. Once the mxd is open it is fine as well. Any suggestions? Thanks ... View more
