Yea I really have not gotten into the representation. I have created a lot of symbols by combining fonts in curious ways. I don't know how the forum will handle it but I attached an Excel sheet that I made some years ago that can be printed out on 11 x 17 paper that contains all the built in ESRI fonts. I printed it out years ago and it has helped a lot to find individual markers.  Well i was all the current fonts as of about 7 years ago.  I added the rotation to the markers after creating all the representations (along with changing the display size), so I know it's possible to do, it's just not cooperating today.  I'm using representations because as much as Esri has thousands of symbols, they don't have ones to fit the needs of my project--namely representing specific wind, weather, and wave features in marine areas.  As far as I've found there are no international standards or even commonly used symbols for these events. ...

Oh I don't think you can change representations. You may have to alter the original symbol to suit and re-represent. Why are you using representation? I'm trying mainly in the Layer Properties in ArcMap. [ATTACH=CONFIG]24012[/ATTACH] ... View more

Go to the symbology tab for your raster.  there should be check boxes on how to display cells with no data. Hi, I'm looking for my problem's solution. I've got 2 rasters: one - with classification's output (*.tif - multiple value: 0-9): [ATTACH=CONFIG]23989[/ATTACH] and one - with classification of water's output (*.tif - value: 0-1): [ATTACH=CONFIG]23990[/ATTACH] I try to insert information from second raster to first raster. I mean: if in pixel on first raster is NoData value and on second raster value in this the same pixel = 1, then value on output raster = 9 (Water ID), but if not - value from first raster in this pixel. Eventually i want to obtain this result in on image: [ATTACH=CONFIG]23991[/ATTACH] Another step, which I want to obtain is fill all remaining NoData pixels value = 2 (Ground ID). Does anyone know how solves this problem? I try to use Raster Calculator, but in my way it's not works. I would appreciate. 😉 ... View more

Open the layer properties for your raster layer. Click the symbology tab If you raster is displayed as RGB Composite Where is says display background value :(R,G,B) Check the box.  There are values there for RGB, either select 0,0,0 or where is shows as and the color selector choose no color.  Where is shows Display NoData as choose no color.  If it is diplayed as Stretched check the Display Background Value make it 0 and the rest is the same that way you won't have the banding where there is not data. I am creating a series of multi-band rasters. Each band represents a variable and so band number is important - it will be used to identify the variable. But sometimes, data for a variable might be completely missing (i.e. I have no raster for the variable, and so have nothing with which to create the relevant band). Missing out this band would mean that the order of the subsequent bands would be altered, which compromises identification of the variable by band number. So can I set a band to Null? Or would I have to generate a Null Raster and use that? If the latter, what would be the most efficient way to generate the Null Raster Band? ... View more

Can you show some snapshots of where you are trying to do this. I've set a feature class representation with a rotation on the marker and I'm looking to remove the rotation, but all the properties are greyed out.  I've had this happen before and managed to make it editable, but today I've tried every combination of new MXD, existing MXD, editing, going through ArcCatalog and nothing seems to be unlocking these properties for me.  Can anyone suggest what I might try?  I'm using 10.1 if it is of consequence. ...

I have done it in the past with 2 mxd's.  If you name your pages correctly and export them from data driven pages as PDFs they will sort themselves out in whatever folder you put them in and then you just select all the PDF's in Windows Explorer and right click and select combine the PDF's It would be a simple definition query for each mxd to distinguish the A and B pages. In our case it got a little more complicated.  Our other side had customer billing information that was generated in MS Access.  So I printed them as a single PDF, extracted them all and create a simple DOS batch command to rename all the other pages with the correct name to sort them alphabetically. I looked at other answer using arcpy.mapping and it sounds like you create two mxds one for each side and then you run the script to combine the PDF files. Is it possible to create a mapbook with alternating data frames (and alternating layers) for each page?  The extent will remain the same.  The index layer would read 1 A-B, 2A-B, 3A-B, etc.  Page 1A would have a topographic base map layer and page 1B would be an aerial layer and would continue on as such.  I could certainly do two different mapbooks and then arrange them but this is a hassle and I want to ensure the pages are labeled correctly.  Is this an arcpy.mapping task?

Could you post an image of what you are trying to achieve? I think what your saying you want is two data frames that each show the same extent but have different features Is it possible to create a mapbook with alternating data frames (and alternating layers) for each page?  The extent will remain the same.  The index layer would read 1 A-B, 2A-B, 3A-B, etc.  Page 1A would have a topographic base map layer and page 1B would be an aerial layer and would continue on as such.  I could certainly do two different mapbooks and then arrange them but this is a hassle and I want to ensure the pages are labeled correctly.  Is this an arcpy.mapping task?

Either of the first two should suffice.  Depends on if you want labels or not for the streets.  You can work with any of them and switch them out as you go to see which one works best.  They are all georeferenced so they will all fit.

Switch to advanced mode and you manually type in the priority ranking.  the higher the number designates which is on top. If you do it with a polyline you will see the check box. Hello, I'm trying to use symbol levels to dissolve town boundaries within the same county. I followed the help instructions, but there are no check boxes in the 'merge' and 'dissolve' columns. This is a file geodatabase polygon feature class, no other layers are in the map. What might I be doing wrong? ... View more

I have done it a number of times without issue.  However, I normally work with dwg My preferred method now is to simply export all the cad features as shapefile and clean it up from there. Note, you should normally work on a copy of the AutoCAD files. Intriguing!  I haven't heard of this problem before.  Any chance you can attach a sample DXF for me to debug with?  or even better, give tech support a call so we can formally log this? The easiest workaround is to stop using DXF...can your CAD techs provide you with a DWG file instead?  They will need to save as 2012 format...2013 support is in the upcoming release.  I can't imagine why reading the DXF is corrupting the file, but I haven't reproduced this in my tests. ...

What I have done when digitizing large and small plats now is I draw a single large polygon around the outside border of the plat. I then use the Cut Polygon tool, classic snapping to parcel Vertex and Edge and simply whip through and cut the parcels out.  As it keeps part of the polygon selected it is actually very quick. no slivers ...

I once had this issue with a lake polygon shapefile I received.  There where some 2000 slivers. I could not automate it.  What I did was go to the first sliver then selected the larger polygon I wanted it to be part of then used select by location to select all polygons touching it.  removed the ones I didn't want merged and hit the merge button and used the big polygon as the merge leader. sounds daunting but with only 900 you might just be better off knuckling down and just plowing through it. I would even suggest symbolizing the slivers with something really distinctive so you can spot them a lot easier and only that polygon layer visible. If you sort your table by slivers first you can simply select and pan swipe/select merge go on to the next. ... View more

I am a little confused by your response.  One on hand you say basing the index on annotation would not work and you indicate you only want to do it with annotated roads. If you do it based on the annotation center point you could snap the resulting point to the road center line before giving it the suburb attributes. What I had done in the past was I had created an attribute for the roads indicating if I wanted it in the index.  Same issue not all the little roads are showing a label. It was someone labor intensive to set it up but nothing to maintain.   If you had some sort of criteria set up to only annotate certain roads you could revisit those roads and break them at the suburb borders go from there. Thanks Robert, The method you have provided would certainly work, however the resulting index would contain ALL the streets that have a name attribute. The map books we create are generally 1:100,000 or 1:50,000 so it is not feasible to label all the roads e.g. in the metropolitan area or in towns as the street density is too high and labels simply will not fit so as a result only some of the roads are annotated. If we created an index containing all the streets with a name attribute and somebody looked up for example Clarence Street and then went to the page on which it is claimed to be and found the location of the grid reference, he/she may indeed find that there is no label for that street as it was too small to be annotated and therefore it could be ambiguous as to which street Clarence Street actually is as there could be several other streets in that general vicinity. So we cannot use the road centreline or centroid data to create the index as such because it would list everything yet everything is not annotated. The index has to be based only on what exists in the annotation featureclass; creating centroids for the annotation, calculating the X,Y and then transferring suburb and page number data into a new field wouldn't work either as it would only list the suburb in which the annotation centroid sits in whereas in reality the road may run through several other suburbs which would need to be listed as well. Take a look at the following example... [ATTACH=CONFIG]23985[/ATTACH] Using annotation centroids to generate an index would result in Springbank Road being listed only in Colonel Light Gardens whereas in reality it runs through Colonel Light Gardens, Panorama, Clapham and Torrens Park. So the problem is getting the index to list Springbank Road as existing in Colonel Light Gardens, Panorama, Clapham and Torrens Park BUT have the X,Y references pointing only to the annotation. ...

Take your original georefrenced image that is correctly located in ArcGIS and export it. Thanks for the reply Eric. I tested renaming the j2wx file, but it didn't make a difference in either AutoCAD or Global Mapper.  The Georeferencing Rectify ran overnight, but finally spit out a result.  Unfortunately, that process took a 700mb file and blew it up to 3.8gb.  I'm not sure if there were some settings I overlooked that could have prevented this, and I'm not sure how it happened since the number of pixels and format stayed the same.  At any rate, that process also did not create a j2w file.  I accomplished that using the ArcScript World File Creator.  This finally made it line up in AutoCAD, but it ran too slowly due to the file size.  In the end, my CAD techs took the original images and georeferenced them in AutoCAD. ...

Create a buffer based on the population.  The buffer analysis tool can do that. However if the population is say 500,000 it is going to make a huge buffer.  and if the smallest is 250 the buffer will be tiny compared to the bigger place. so do some math and create a buffer attribute to determine the size of the buffer.  Perhaps taking into account your largest location and considering its full size to be 100%.  make its buffer size at 100 If that size is 123000 then 100%=123000 or 1% =1230 population.  so a commmunity of 1230 would get buffered at 1 to you calculate the size of any smaller community based on that percentage.  You will have to play around with units on the buffer to determine what size would look good.  If your map is representing 100s mile across perhaps a good size for the big one would be 100 decimeters (200 dm diameter) have another attribute make it a yes/no.  Do calculations to determine if the population has increased and make those polygons yes and the others no.  then you can symbolize the polygons based on that attribute. Hi I'll will find out the difference in population between year 2000 and 2013. I have a feature class file with the population in year 2000 and 2013 that are connected to the municipal number and that is a point theme. What I want is to have is a buffer zones around each point and the size of the buffer zone is determined by the number of residents that each point has. I the population has increased the buffer zone will get a red color and where the population has decreased the buffer zone is  will be blue. Is there anyone who can help me with this? Whether as a model in the Model Builder, Python or toolbox. Thank you in advance Tom Anders ... View more
