I'm relatively new to automating processes with ArcGIS. The overall goal of the model is to first isolate the road network of a user input town/city from a state/provincial road network file and then ensure that none of the segments in the new town/city network are greater than 500m. The logic...

Desktop 10.3.1GCS: WGS 1984 Created a Buffer of points based on a pre-specified radius from the points attribute table. It appears all of the buffers were created with a decimal degree unit of measure.... How do I change the units of the buffer layer to miles? أكثر...

I need to perform a cost-distance analysis and cost allocation analysis for a tsunami evacuation model. As only open and free available data is used, it would be also good to use open source software only. Since Grass GIS and SAGA tools do not seem to cover a cost allocation analysis, I tried...

I've recently come across some data that has been labeled "hypsography". I looked it up and it sounds like topography. But this data source has data labeled "topography" separate from its "hypsography". What's the difference? I've read the wiki for 'Elevation' and its starting to sound like all...

I am trying to label a single point with multiple labels, based on the attributes for that point. For example, if one of the attributes is equal to 1, I want to label it with a specific text string; and if another attribute is equal to 0, I want to label it with a different text string, etc...

Recently, I've been playing around with the idea of creating my own set of 3D symbols to use in ArcMap specific to the line of work that I'm in. I'm wondering if anyone here in the community has any experience doing this and what software they use to create the symbols. I am familiar with...

I've got a custom web application using OpenLayers3 running GeoServer (2.7.1) as a back-end. I've added a world-wide temperature GeoTIFF as a test, and it renders in a strange way. If I move the map to pan eastward, the GeoTIFF fully renders over the entire map. If I move the map to pan...

I am trying to build a web app where users can use OpenLayers to draw features and then save them either as a download or write to a file on the server which I can collect when I need it. I am happy with the OL3 bit so far. From reading around it seems AJAX is the way to do this so I have...

I am using Esri Javascript API to display points on a map that are pulled from a json object. Everything is working great, although i seem to be having issues trying to figure out how to get the map to show all the points (zoom to an appropriate level) at once. here is my code any help that can...

I have got a leaflet map with Geojson layers : I use jquery Autocomplete to search an entity by name or id, I have no problem with that. I need your help because I'm not able to refer to a specific point in my layer (without a click on the map). Ideally, I would zoom in on it and open a popup...
