If your looking at it in the layout window it should print the same relative size as it does there.  What you can do is export your map as a pdf.  say your paper is 36 x 24 the pdf will be that size. then print the pdf to your local printer in 11 x 17 or 8 1/2 by 11.  Have it tile the pages and that will give you something of an idea how it will look on a full size page. FedEX is probably going to charge you an arm and a leg so you want to get it right the first time. Thank you very much Robert-- this gives me good info on how large the paper will be. One concern that I have is that I expand something up on a plotter will it make the font all weird looking? I continue to know very little about this process and if anybody could recommend tutorials and search terms for 'Esri support' that would be great. ... View more

What are the dimensions of the area you wish to show? For the sake of argument lets say it is a polygon.  Basically if it is 11 acres and it is a perfect square then it is roughly 479160 ft Square or  692.21383979230002101435931902876 ft on a side so if you have 1 inch = 20 feet then 692.21383979230002101435931902876/20 = 34.610691989615001050717965951438 inches of paper space on each edge. So in your layout window adjust your layout size to 34.6 (not exact but close) on each side then zoom your polygon in so that it is perfectly matching the edges of the paper space. So if you know the dimensions of your are in feet make your layout window adjusted appropriately Say your 11 acres is 300 feet on one edge then it would be 1597.2 on the other 300ft/20ft/in = 15" by 1597.2ft/20ft/in = 79.86" Keep in mind that is going to be the size of your data frame in the layout window.  Your plotter may need at least .75 inches on the edges of the paper.  As it would be on a roll you would not need to worry about the other edges. Basically take the lengths in feet and divide by 20 to get the sizes needed for your paper then put the edges of the area right on the edge of the paper. Hi! as always Esri support is hard to use so I am just doing my best to put this question where it belongs. Thanks for your patience. Anyhow.....I need to make a map with a scale that is 1 inch = 20 feet.  It will be of an area that is basically square and roughly 11 acres.  I suspect that this will require me to go to some business (such as Fed Ex Kinkos) with some oversized printer in order to print it out.  Is this possible to do this with ArcMap 10?  Could anybody give me general guidelines on how to make a map of this scale? Could anybody give me suggestions of where to find information on this support website on what I want to do -- like for instance suggest search terms? ... View more

You wrote that none of the polygons overlap.  then you write that you need a line to divide planning jurisdiction equally between each city where they overlap. Well you could simply create a new set of polygons where the overlap occurs and draw a line equidistant between the edges of the polygon. I'm not authorized to upload my work, but I have four polygons, one for each city in my county; none of the polygons overlap.  I need to develop a line to divide planning jurisdiction equally between each city where jurisdicitons overlap (polygon). ...

Essentially there are 4 types of autocad data you can export. lines polygons points text Text will export as a point. There are many features that will export as multiple features.  For example Blocks will export as points, lines, closed lines, hatch polygons etc. Instead of exporting the AutoCAD dwg as shape files try opening the dwg directly into ArcGIS and do queries to select various layers in the drawing and export them to your database. There really is no simple way for me to explain the entire process.   A good share of my current career has been spent converting AutoCAD drawings to ArcGIS.  There are a lot of tools built in for dealing with AutoCAD but I have found it is simple grunt work that gets it done the best. ...

Export your events as a shaprefile first or to a database I have a shapefile of LA county with a single polygon for each city. I also have a table with x,y data that has been represented and the city names for each event match with the city names for the polygons.  So how can I combine the point data to the polygons to do polygon analysis? Trying to join doesn't work since there are several events for each city and only one input for each city ... View more

Export as a shapefile.  Then import the shapefile in AutoCAD instead However, I have yet to see anything that will import your map into AutoCAD so it will look like your ArcGIS did.  Points will be Points, Polygons will be hatches and Polylines will be lines. Hey there, I have a client who is requesting data in an AutoCAD format with the attribute data beign vital to display in AutoCAD 2013. I exported the requested data to a shapefile and used the geoprocessing tool, Export to CAD, thinking it was that simple. Well they didn't not see the attribute data along with the points. I then searched the forums and following threads: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//00100000001r000000.htm http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001000000073000000.htm Those pointed me towards the seed file creation and also the extra fields on the shapefile. I did these steps and know the client can't even view the file sent over. And I can't see the file in my AutoCAD. It as if there was no data in the export.  I'm using ArcMap Info 10.0 SP 3, AutoCAD Lt 09 at my work station? They have AutoCAD 2013\12 I believe. Questions are what level of AutoCAD does this tool support? Do we need to download the AutoCAD plug-in at both workstations to view the data, being exported by the geoprocessing tool? Do I need to create a geodatabase feature and annotation features? Are there any more steps or tricks I might be missing, any help or thoughts would be apperciated. ... View more

If you have the Publisher extension one of the best ways is to make an  ArcReader Published Map File and they can have full viewing access to your database but they cannot edit it.  They can also then have their own PMF on their machines and can actually mark it up and it will not have any effect on your database or your MXD's The ArcReader program is free and can be installed on any machine. You may also want to explore ArcGIS Explorer Desktop as a possible option.  Is it possible to share a map to a group as read only, without letting the group members be able to save the map? I understand users being unable to make changes to what is uploaded, but I'd rather not let them save their own copy. ... View more

All I have to say is wow! Automating a  raster mosaic to run several times an hour.  It should be possible  but  i would think would be hard on resources. Thanks for the suggestion.  One thing I forgot to mention, though, is that this all has to be automated. This mosaic dataset will be updated several times per hour with new versions of each regional image, and I will be maintaining about 3 hours of imagery at any one time.  Each time I import a new raster, I would have to apply the mask, correct?  Is there an ArcPy function I can execute to mask an individual Mosaic Dataset item? Thanks for the help, Jason ... View more

Convert your angles to Long Integers or double precision 0 to 360.  and use that new rotation field in Data Driven Pages for the rotation field. Just made the switch over to 10.1 and been running into non stop issues... One issue is with the Stip Map Index Tool, unlike the strip map tool from 10.0 the tool seems to be unable to calculate negative angles. This makes it unable to properly display with data driven pages, sometimes flipping my layouts almost completely upside down...If i were to present on of these maps my north arrow would then be basically pointing south? I've tried many methods of troubleshooting this issue and non seem to work, been using this tool for years never ran into issues till this new release.. So anyone else running into this issue or know how to solve it? Or should one just revert back to 10.0 ... View more

Perhaps you could get new copies. Do you need the photos to be a specific year? I know in my state we  have air photos dating back to 1991 readily available, and Older I suppose if I went digging for them. Lastly you could instead place a black polygon behind the photo.  That would fill in those blank spots. simply draw polygons in around the exposed area.  The way you did it with orange is great to see them. Then just put the polygon layer lower than the raster in table of contents. ... View more

cropping may be your only viable solution. Those portions in the middle that are that way may be because the scan showed them as so dark they show up as background color. IF you need the edges to be sharp and cropping does not work you can create a mask.  meaning make a great big polygon that is a hole in it that is a smaller than your raster and essentially just as a mask over the image. A little cumbersome but it would cover it up. Thanks for the responses. Yes, I tried it the black collar has the value 0. So display background set to Zero. [ATTACH=CONFIG]24208[/ATTACH] The problem some of the areas inside (valid) also have zero values. So holes are showing up while the collar is removed (minimized). [ATTACH=CONFIG]24209[/ATTACH] Seems to be the problem repeatedly for different datasets. ... View more

You could also incorporate some good old Physics here. Unfortunately I am a number of years out of college but there are basic formulas for calculating how much engergy it takes to go a certain height on an incline.  You can factor friction and resistance out as it would be the same up or down. So if you have the slope your should be able to determine roughly how much energy is needed to get a given mass up a 3% slope to 100 feet.  You will then have potential energy at the top to figure in as an energy savings going down the hill. Hmm you do have variables on engine size, hp etc. Please keep you findings posted here this sounds interesting and when you do knock it out of the park you will have a great basis for a paper for the user conference. ...

You have Spatial analyst so you have the proper extension.  Use the Int tool. Converts each cell value of a raster to an integer by truncation. Try it on a copy (disclaimer) Hi, I have an RGB image that visually works as contiguous, single values classified data, but it was delivered to me as an RGB.  I need to convert this into a float or integer raster so I can make isolines and compare this with topographic contour lines.  I have Spatial Analyst but I am not familiar with Python and would prefer not to code anything or write a formula.  This will sound blunt, but if you have an answer but it involves either of these please don't post it, I don't have the time to finish developing ESRI's software for them.  I need point and click, GUI tools, which is why I purchased the software.  I don't have the budget for an exhaustive approach.  If there are any extensions that can make this easier please list.  I'm looking for something that specializes in Raster conversion (I already have Spatial Analyst, yes I see the Map Algebra tool) but haven't found one yet. ...

keep in mind different formats have their own different drawbacks as well. For best resolution you would consider one that does not compress the image and take samples and generalize an image based on those next to it.  But the images are a lot smaller. SIDS efficiently show very large areas but can be cumbersome to work with. tiff and bmp have better resolution but tend to me much larger.  You should try several formats and see which one will work best for your needs. I'm upgrading a python script so that it'll function in ArcGIS 10.1 and as such I have the opportunity to change the raster format. Currently, the rasters are saved in Esri's grid format which has a few drawbacks. The most notable one is that grids cannot be stored in a directory structure with more than 120 characters (including the name of the raster). I believe this is no longer the case starting with 10.0; is this true? Also, what is the most efficient raster format when using Spatial Analyst? Is it Esri's Grid, Erdas' IMG, or storing them in a file geodatabase? Efficiency, I'm defining here as the fastest processing time but I'm also concern to a lesser degree with storage size. The output from these steps will be single-band and either integer or float. David Sinton [email protected] ... View more
