I want to calculate cumulative field values using an case field from another column in ArcGIS 10.4. For example, if I have an "ID" column and "Count" column inside my attribute table, I want to calculate cumulative values for each year separately. I have used this: How to: Calculate cumulative shape length values of a feature class using the Field Calculator I can do that if I select all rows with the same ID and run the field calculator, but that is a lot of manual work, so I want to use "ID" field as case field. What is the best way to do that?

Hello. I want to create an ArcGIS online map or application with my free account. I want to place some filters so I can sort and filter data.

I am trying to export a large map 174in x 96in from ArcMap. The map is really big so when I set this custom format from Print Properties and try to export the map I get the message: "ArcGIS Desktop has encountered a serious application error" and the application being closed. Why this happening and how to solve this problem? I just want to export this large map in PDF.

I have a Digital Elevation Model and polygon shapefile and I want to make an effect that polygons follow terrain structure according to DEM. If I just overlay it over DEM the polygon will be flat. I know how to do that in ArcScene, but I want to do that in ArcMap and not sure how. I have tried with Window\Image Analysis but without success. I have attached one example from Google Maps where forest polygon follows terrain structure.

Yes, this could be the final step, but If you read carefully my descdescrip the main problem is that I have a parts of streets defined by intersecting streets, and each part have information about number of potholes.

I have a table which contain fields "Street", "From", "To" and "Number of potholes". "Street " showing the street line where the potholes are. "From" and "To" are street names which define part of street where the potholes are. "Number of potholes" is number of points which I want to place on defined part of line (between "From" and "To"). I want to do this using ArcGIS 10.4 . I have idea to download street lines from OpenStreetMap and to geocode each street and select street lines by location. I am not sure about steps after these.

Exactly. From each census tract to all zoning types... How I can do that using Near Table tool in ArcGIS 10.4? When I run it I always get the same results, just the one nearest zone...

Thank you Dan, but this is not completely what I need. On this way I have just one distance to the nearest zone, no matter which one, but I need a new distance field for all zone types for each census tract. For example CENSUSTRACT1 have a information in distance fields "A" (which mean distance to the nearest zone A), "C" (which mean distamce to the nearest zone C), etc...

I have a two polygon shapefiles, one shapefile is a zoning and the second one is a census tract. Now I want to calculate distance from boundary of tract to closest boundary of each zone type (R, C, etc). Because of that I have dissolved all zones according to zone type and now I want to have in each census tract information about nearest distance to the all zone types (distance to C, distance to R, etc...). Also I want to have a zero distance value if each tract contain the zone.

Thanks for this, but should I use ONE TO MANY solution or ONE TO ONE? Also what would be the result, one feature with nee columns about nearby feature, or a couple of features with information about each?

I have a polygon shapefile and want to have a information for each polygon about all nearby polygons that share a boundary with them. For example, I have a polygone P1 and three nearby polygons P2, P3, P4 which shares boundary with P1. So, in attribute table of P1 I want to have all attribute table information about P2, P3 and P4. How to do that using ArcGIS 10.4

I want to find USA water hardness shapefiles. I have searched for it from here: https://www.epa.gov/waterdata/waters-geospatial-data-downloads but without success. Is there any good data source from where I can download these boundaries?
