Who are the people served by your city’s transit system? And who isn’t, but should be? How does transit change throughout the day? And what is the best way to analyze service areas? As urban areas are investing more time, money, and energy into creating public transit systems that increase...

I am trying to clip a point layer with a polygon layer. My polygon layer has multiple polygons (e.g. country with different states). I am wanting to clip the point layer based on the different states contained in my country polygon layer. I realised I could do it manually by selecting the state...

Any help with this would be appreciated. I am projecting a WMS-layer on a map using OpenLayers and Geoserver. The next thing I want to do is to display info on any given feature in my WMS-layer in a popup whenever a user clicks it. This is all working fine, but my problem is that whenever I...

INASAFE seems like an interesting QGIS plugin but as I wade through the docs, I really need some sample data to play with in order for me to understand. There is a tutorial which uses Indonesia data, but I can't find that dataset either. If anyone is using this and has any example datasets, it...

I'm using mapserver to serve an overlay of weather data onto a google map (V2) and the weather data is not displaying where it should. The image below shows the problem i am having. The black lines are the land border of Alaska, as you can see, they do not line up. The brown lines represent...

I signed up for an ArcGIS for Developers Free Development and Testing Account and when I signed into it today, it said it was suspended and or expired? I thought the account was free for life? Do I need to purchase a subscription like you need to do with the 30 day free trial account? I...

In ArcMap 10, I realize I can manually do this after the polygon feature is calculated by right-clicking the column in the attribute tables to calculate geometry or create a python script to do this but neither of these seem to allow me to automate this for new features without having to take...

I know this was partially address here, but it was not specific to ESRI products. I want to find some place to create and host map services with ArcGIS Server and ArcSDE. ESRI cloud options are bit pricey for the initial startup and testing of my project. Anyone know of lower priced...

Now and then I run into the following problem: I start debugging the Add-In and breakpoints are ignored. Almost seems like the communication between the IDE and the component is not working. My problem is that the last time this had happened I resolved it and now I can't remember what I did...

I am trying to overlay a topographic map that is a raster and a road shape file. The road shape file was originally not defined. I defined the projection to NAD_1983_2011_Contiguous_USA_Albers and I did the same with the raster through it's properties window. I then used the project and made the...

I'm using data driven pages (DDP) in ArcMap 10.3. The index layer is a polygon feature class and I would like to know the scale that each data driven page exports at. Ideally there would be a way to append an attribute to this layer that indicates the scale for each page (200+ pages). (I know...
