Hello all, I have a problem converting my raster calculator values into polygons. When I convert these raster calculator rasters into polygons, it not only gives me the raster I ask for, but also a large polygon. This makes it hard to intersect the rasters with my road files in order to determine how many miles of road the new polygon made by raster to polygon intersects. I am having a somewhat difficult time explaining what I am meaning so I have attached some pictures. When I make my polygon, I would like the new polygon to only contain the yellow parts, not the blue parts. Hopefully the pictures help make some sense of this question. In the images, the blue and yellow is the original raster and the pink and gray is the new polygon made. I do not want the pink part of the new polygon but only the gray part. Thanks for any help and sorry if this makes no sense. ... View more

Hello all, I am fairly new to GIS, and have been using the Network Analyst to route from one city to another. The routing part is going fine, but when ArcMap gives me the driving distance, it is way off. For example, I routed from one city to another and got a driving distance of <0.1 mile. When I used the measure tool to measure the distance between the two cities in a straight line, I get 286 miles. The data is all using WGS 1984 coordinate system if that is of any use. Any help? Thanks. ... View more
