As I predicted, a new global map of Pluto has been released that incorporates the imagery that has been downlinked so far from the New Horizons flyby: with gridlines, without gridlines. If nothing else, the equatorial projection demonstrates how much of Pluto's surface was not seen during the...

The next release of our map design and data visualization tool, Mapbox Studio, will do away with code-based styling and introduce a totally visual interface. Here’s a video showing off some of the basic styling tools: Finding the right balance between ease of use and power has...

I am transferring a large dataset from MapInfo to QGIS and I want to be able to create a column in the MapInfo attribute table that differentiates features with different symbology (even if it differentiates with a number or letter), that way when I add the data to QGIS I can easily change the...

I'm creating json to create a custom printout using the Export Web Map task on an ArcGIS server (v10.2). Everything works as expected apart from labels are not showing in the generated printout. The layer is a feature layer and the shapes in the layer appear fine but the labels don't. The...

It just came to my mind now that since when developing web based application we use online libraries, we reference to them, is there a chance (if it makes sense) that those libraries be relocated to another sites? Say perhaps you always used to find your resources(libraries) on a particular site...

Bonjour à tous, Je découvre QGIS peu à peu et je me retrouve confrontée à un petit souci que je soupçonne simple à résoudre - bien qu'agaçant. Voilà, je souhaite créer une carte de localisation des adhérents par commune. Je possède une couche avec des points (localisation des adhérents au...

I´m trying to add a view from postgis using QGIS, what´s facile. The problem is that it´s taking too long to load it and to perform any kind of operation, for example, as simple as counting rows. It´s a complex view, with 627 rows, and large geometric atribute. Is it possible to create indexes...

My Objective: I would like to use GDAL to convert a GeoPDF. I want the vector layers as shp files and the raster layers as tif files. I want to do this in a programmatic way. The Problem: Naturally, the command to convert a vector layer differs from a raster layer. And I don't know (again in a...

I have a series of tools that I need to run in ArcGIS to hydrologically condition my DEM, but the first step in this process is running the Breach Depressions tool from Whitebox GAT (I have found that this tool works really well for breaching streams across bridges and dams). Is it possible to...

I need to implement, within this very simple piece of code, the option that replicate the "Clip to output graphics extent" available from the ArcGIS 10.0 Export Map UI standard command. Is it possible? The purpose is to iterate a list of MXDs and export them their layout view to a graphic...

With QGIS, how can we analyse an electrical network to find loops?Using Python is not a problem, however there is not a solution in the QGIS Python API. The QgsGraphAnalyzer has dijkstra and shortestTree functions, but no loop finding function (QgsGraphAnalyzer Class Reference). Example:The...

Sorry, but I'm a bit new to the whole GIS world, and though I am making great headway drawing polygons and such in Bing Maps, I am currently stuck. In our SQL spatial data, I came across MULTIPOLYGON data, where all the lat/long values are very large numbers (6 digits for latitude and 7 digits...
