I am creating a workflow to iterate through a batch of rasters and perform several different operations-at the end of this workflow, I would like to add my rasters contained in a geodatabase to a constant raster to get a cumulative raster that would be stored in a new geodatabase. I'm throwing...

Distribution utilities can never guarantee uninterrupted power. A heavy storm, a fallen branch, a car accident or even scheduled maintenance can easily down electric lines. While disruptions are inevitable, what sets an agile and leading utility apart from the rest is its ability to quickly...

Assigning a style to a geojson layer but it is visualising with the aforementioned style as well as the default blue style assigned to geojsons. Can't work out what is causing Global Terrorism Attacks Global Terrorism Attacks أكثر...

I'm running ArcGIS 10.2.1 and I need a way to visualize the state tree for my versioned SQL 2012 database. I've previously used the GDBT tools but there isn't an option available from ESRI that will install on a 10.2.* set up. Does anyone have any suggestions? I'm not a big fan of hacking my...

I am using leaflet in order to render a map. I created a map with markers and i dont know how to implement the Event Listener 'onClick' on each Marker. My code var stops = JSON.parse(json); var map = new L.Map('map', { zoom: 12, minZoom: 12, center: L.latLng(41.11714, 16.87187) })...

I have a REST service that returns shapes as json. The shapes represent various natural features. The problem is the precision of the coordinates. Currently, nine decimal places of precision are returned for each vertex. For these features, that level of precision is ridiculous and one or two...

I have enabled jsonp in geoserver/WEB-INF/web.xml. It appears in my layer preview in geoserver. I cannot seem to get my geojson layer to show up in my map. The tiles show up but with no layer. Not sure where to go from here. I have been searching through other peoples coding but no luck...

I'm using ArcMap 10.3.1 from a basic desktop concurrent use license. The problem I'm experiencing occurs when I load an existing mxd (creating using 10.3.1), and then try to switch from data view to layout view. When I try to switch views, the program crashes. I have tried to delete the...

I have a shapefile that has the outlines of the United States and I want to create hex grids that over that layer. I tried using this function that will create hexes over a layer. I created an empty table and then added a geom column and then ran the custom function as shown. CREATE TABLE...

In Qgis python console: I want to populate a list with compositions names, like in Composer Manager, but I can't figure out how to get the names (titles). So far: composerlist = self.iface.activeComposers() And I get a list of QgsComposerView objects. Now I want something like that...

I am attempting to create my first leaflet map. I am using OpenStreetMap tiles and adding geojson features as overlay layers. I have been following tutorials with much success, until I started trying to add labels. I would simply like to add static labels to several features, and be able to...

I'm using the MasterMap ITN Dataset and I was wondering if there is a difference between converting the data using Productivity Suite or InterpOSe? For example, would I be able to carry out all tasks/analysis regardless of which software I used? Thanks! أكثر...

I’m excited to welcome Moritz Kobitzsch to the team! Moritz comes to us from the Karlsruhe Institute of Technology where he recently finished his PhD in efficiently computing Alternative Routes. At Mapbox he will help to push Mapbox Directions forward. In his free time, Moritz can most often be...

I am new to this, thanks in advance for your help. I have data downloaded from ftp://ftp2.census.gov/geo/tiger/TIGER2015/ and I would like to learn more about how I can query that data for the different layers it offer. Here is what I did so far:1- I unzip the downloaded folder.2- I convert...

I have an application which has perform a HTTP request (which will handle some map transformations) before starting fetching WMS tiles from server. Is there a way to pause TileWMS auto-refreshing after dragging the map? Setting invisible or removing and adding the layer will work, but I don't...

Unfortunately it's possible to apply an invalid SQL where clause when using arcpy.MakeFeatureLayer_management. This can cause issues later in a script. For example, I created a feature layer and subsequently tried to apply Snap_edit to the layer, which caused IDLE to crash without throwing an...

I'm trying to intersect large datasets in OGR and python using SQL queries like ST_Intersects and ST_Contains. These operations run very fast in ArcMap but I'm designing a system to automate them, hence using OGR and python. My code is taking forever to run (days). I've read recently that...
