I am using a SRTM 30 meters for slope and elevation. When i'm using this 30x30 rasters to generate contours i set a 30m equidistance for contour, and the results are ok. Now i'm wondering if it's wrong to set a 10m contour from a 30x30 DEM like ASTER or SRTM. أكثر...

In reference to my previous question. I am looking for the benefits of telling SQL Server your data is spatial. For instance, I have a duplicate of that table generated by the Shape2SQL tool (see previous question). The major difference is it is not a spatial table, but I have a field where I...

I'm trying to create contours from a raster using GME but continually get this error message regardless of what I try in terms of moving the input raster around or output destination... any thoughts? Thanks! Found R here: C:\Program Files\R\R-3.2.1\binTo switch to a different version of R use...

I'm writing a script to automate post and reconcile a target and edit version. I consistently get the warning message "The reconcile process was not performed. The specified target version has no edit versions to reconcile with." I double checked that in the Administer Geodatabase tree view that...

Is there an analogue of ArcGIS Dissolve function in R? I need to dissolve the overlapping polygons and create a single part object. I was trying to use gUnionCascaded, but it creates a multipart object. Is there a function in R to do Multipart to singlepart? أكثر...

Is there a way using ArcGIS 10.3, when you have points for Surface Well and Bottom Hole... with API numbers, match up the API numbers and have a "LATERAL LINE" be drawn without hand drawing in each one? أكثر...

When I add GPX layers (this one, for example) through the GPX to feature tool in Arcmap, the layer shows up as points logically. Then I try to convert these points to a polyline (in this case bicycle routes) using the points to line tool but the lines always show up strangely, like this:Sorting...

I am working with raster/brick data in R and running into memory issues. I am basically trying to use raster objects to perform some simple agent-based modeling, but the objects keep increasing in size for reasons I can't understand. Below is some code that demonstrates what I am talking about...

I have two rasters, one has a 1 km resolution. The other has a spatial resolution of 30 m. This latter pixelwise is a classification. I want to overlay the 1 km raster on the classification raster and extract for each 1 km pixel the distribution of classes corresponding to the 30 m...

I have a map application that harvests it's map layers from a JSON string. I've managed to use the following code to show the map layers when a user clicks on a layer name in a table of contents but any success to use IdentifyTask to return individual features when someone clicks on a map layer...

The instructions here: https://hub.qgis.org/wiki/17/Arcgis_rest are straightforward, but I'm getting the same 1000 features regardless of extent (with the 1000 feature outside the viewable map extent in QGIS). My current map extents should only return back a handful of features. Does QGIS pass...

I am looking for ways to learn querying for SQL Server Spatial (2008/2012). I have a table created from Shape2SQL and have been trying to run a simple intersection query to get results from that table that fall within a polygon I am creating. I got as far as: declare @poly geometry =...

I know it's very simple but anyway: (Asked also at stackoverflow) INPUT: Regular OSM buildings .shp table PostGIS Point location RADIUS (around above location), lets say 500m. RESULT: I want to get back all corners from all buildings within this radius from location, that ("WHERE") they...

im wondering if its possible to create a Time-Space Map in QGis or ArcGis. As i already found one can use rubber sheeting in ArcGis to create such an effect but as far as this goes you are about to need a huge ammount on Vectordata to create a useful map. My task is pretty simple, i have a city...

I am very bad at python and I can't even get this script to work and the worst about this is that its really small script. Lets say I have a shapefile in C:\temp\test.shp and I want to list all the field names in that shapefile. Lets say a featureclass with 4 fieldnames: TYPE, NAME, SPEED...

I'm looking to disable being able to move the map in such a way that one can move outside of the map area: I don't want to be able to see the surrounding white areas when the map is dragged. I have turned off wrapping as I don't want any horizontal duplication. Code: // Create a map in...
