My task is to upload geojson, add data from corresponding csv, drop some columns, then save it back to geojson. However, after I did everything, added csv data (gj.join(df) ), etc, I can't save it to geojson getting this Keyerror: KeyError Traceback (most recent call last) in () ----> 1 x...

It's very unfortunate that Google Maps Classic no longer exports routes as a KML file, and Google Maps Engine Lite isn't as easy to use. So I was wondering if it were possible to somehow "rip" a route drawn in Google Maps Classic, possibly through some local JavaScript. Thank you...

For those who are new to the programming side of GIS, I feel that a lot of great tools and resources are inacessible. I am interested in GUI based wizards for handling geoprocessing with libraries like gdal and ogr. Any tips? أكثر...

I have been having trouble trying to come up with a python script that will go through a polyline feature class representing a river system and split all the streams intersecting with a central river at distance of 2km. The added difficulty is that any given stream can be made up of multiple...

(I asked this in SO General - but then thought it might be better here - sorry for the cross-post!) Using the API, is it possible to turn off the 3D terrain in the Google Maps satellite view? I'd like to get the imagery without it being warped by the 3D surface. أكثر...

I am using R LeaftLet package to create a interactive choropleth of the US Map. There are several tutorials online and I am able to create interactive state level map with pop up and zoom. Also I was also able to create a separate zip code level map again with pop up. Now my question I...

As the title says I would like to draw a Google Map between two cities crossing a mountain pass in the Western USA. That part I can do just fine. What I would then like to do is print it at the above specified scale (am I using that correctly here?): 1:160 - which is N scale in modeling...

I'm fairly new to leaflet and web mapping in general. I was curious if there is a way to set labels to only appear at a certain range of extents. The point data layer I have clusters too much preventing any legible labels. It also makes the map look really cluttered. I have been using the...

Maps are composed of carefully selected and simplified data: the maker’s challenge is to include context and data without adding clutter. To make this task easier for cartographers, designers, and developers, the new Mapbox Studio, coming this fall, includes an intuitive new way to browse and...

I just exported my image from ENVI into Geotiff data. My coordinate was so strange even though i have defined projection by UTM, like this 122,845531 -1,298482e+016 Decimal Degrees.You can see it in the image I uploaded. Any idea? Thanks أكثر...

I am trying to run a model which iterates joining multiple tables to a shapefile and export the resultant shapefile after each iteration. The model runs successfully but after each run, only the last iteration results in a meaningful shapefile. Or all the iterations before the last one, the...

I have multiple dbf tables in a geodatabase to be analyzed. I found this post Reading File Geodatabase using R indicated R is a potential tool. But it is not clear how to loop through the folder containing the dBase files using R. Anyone can give an example? Or suggest another effective...

I am trying to get popups to work with a featureLayer in MapBox.js, to no avail. Here is my code: var pliOptions = '<h2>A ferry ride!' + ' Test Data'; // Since featureLayer is an asynchronous method, we use the `.on('ready'` // call to only use its marker data once we...

I like to go to mountain, and got lots of GeoTIFF maps, which I can convert to other formats with GlobalMapper (JPG+JGW, ECW, ...). However, I haven't found an Android app to: - show these raster images - show my position, at the same time I tested QGIS Mobile, but it did not show my...

I am having trouble saving outputs from CellStatistics but only when I run it on a list of rasters. This was working on python 26 but not 27. I know this example is nonsense, but: env.workspace = "G:\\Faculty\\Mann\\Historic_BCM\\Aggregated1080\\" relevant_tifnames_year_i=...

Bonjour à tous, Une question toute bête mais un vrai problème pour moi en ce moment: J'utilise ArcGis 10.1 et quand je veux exporter ma carte, les options (style nombre de ppp) n'apparaissent plus... (Je peux encore choisir sous quel format de doc je veux exporter) Pouvez-vous m'aider...
