I'm trying to make a model of surface runoff of rain water. I'm using GRASS GIS function r.flow, which generates nice smooth lines of runoff. What I need is edit these flowlines someway to avoid crossing between lines (see picture). As a input data, I'm using DEM in 5 meters resolution, which is...

I want to collapse a leaflet control on my map. I have the current code: var legend = L.control({position: 'bottomright', collapsed:true}); legend.onAdd = function (map) { var div = L.DomUtil.create('div', 'info legend'); div.innerHTML = "<h6>DISCLAIMER: text</h3>"; return...

This issue had only started in recent days. Just wondering if anyone else has come across this before and might know of a solution? I have multiple mxds that contain layers that normally live in a folder called "Data" within a project folder. So the source for these shapefiles would look...

PostgreSQL's ST_Distance_Sphere function calculates the distances on earth: float ST_Distance_Sphere(geometry pointlonlatA, geometry pointlonlatB);In its documentation, there is a peculiar note: This function currently does not look at the SRID of a point geometry and will always assume its...

I just started playing around with stacking NDVI images from different years into one RGB value and am unsure how to read the photos or analyze them. The image on the left had R 2011 G 2011 and B 2003: I'm assuming the light grey and white means high vegetation/little change, the black is low...

I have two feature class and the requirement is to intersect both of them in flex.I'm querying on one feature class, getting its geometries. I tried doing union of all the geometries of the layer into one geometry using the Geometry service but then it doesn’t seem to work.Is there any other way...

Are there alternatives to Google Earth that will display the latest satellite images and can add pinpoints and are relatively intuitive? It would be nice if I could possibly add shapefiles on top of the satellite images. I have tried ArcGlobe which is interesting but many layers like...

So far I have been using OSGeo4W shell (or OSGEO install) as really convenient way to use python together with additional packages, namely gdal, shapely, numpy, scipy and matplotlib. I was happy till I came to the point where I need to start use also pandas and VTK packages. I came across...

The output I get from QGIS 7.0.1 for an ASCII DEM file doesn't seem to be a correct format. It differs from the format I get when I download a DEM file from webGIS ( http://www.webgis.com/terr_us75m.html) . I have an application that will accept an ASCII DEM file as input. When I input the...
