Currently i have created the layer in Geoserver by configuring a native SQL statement, there i am getting the route geometry details from DB by following query SELECT ST_MakeLine(route.geom) FROM ( SELECT geom FROM pgr_fromAtoB('ways', %x1%, %y1%, %x2%, %y2% ) ORDER BY seq) AS route...

I'm using ArcMap 10.3. I have a layer of different land use types. I found out that many polygons overlap each other and as a result the same polygon have two different land use types. Thanks to @radouxju's answer, I built a topology for the land use layer (with the mustn't overlap rule)...

I would like some help here... I can't figure it out. I'm very new to QGIS and I'm trying to create a cartogram for my final project. However, while I have my data that I'm going to use and the shape files (provided by the US census) for the US, I can't seem to get it to generate a cartogram...

I have a layer of points, that I hope to connect to form a polyline(s). The layer looks like this: I am hoping the end results traces the network that was originally used to construct the points: Background:I am using ArcMap 10.3. My workflow has been to turn the original polylines into...

I'm a beginner at QGIS and I'm having trouble aligning my shapefiles. I have two datasets: one originally in WGS84 (lat/long) and another in Corrego Alegre/UTM zone 24S.I need to convert the second into WGS84 for my work, however if I go to Vector -> Data Management Tools -> Define Current...

My customer requirement is to support a MrSID image directly in ArcGIS Mobile. The details are sketchy but I think the intent is that they want a local background raster Map while the ESRI.ArcGIS.Mobile.Map gets used to handle other tasks (?vector display, updating GDB?). The Map control...

I am relatively new to the ArcGIS-Python environment and want to calculate elevation raster slope. But it says "ValueError: setting an array element with a sequence". Below code is what I have. import arcpy, numpy, mathfrom numpy import *from arcpy import envarcpy.env.workspace =...

I am trying to identify the start and stop of a particular incident- these are indicated by the unique values 0,1,2,3,4,5,6. 0 represents no incident- therefore in order to identify when an incident starts and stops and only retrieve these data records (i.e. incident 1) I would like to know...

I would like to implement a function that highlights polygons as you mouse over them. Just like this: http://bl.ocks.org/javisantana/8313604 with the added function that it will highlight multiple polygons if they are overlapping. The code in the example above works fine, but I can't get it to...

I downloaded a bunch of wpts from my gps. I converted them to .SHP format with a CRS WGS 84 in QGIS, and started a new project. I then exported some satelite imagery from the internet as a tiff and imported it as a raster in my project as WGS 84. I have CRS 'on the fly, enabled, but I still...

I have downloaded the Blue Marble dataset, and it consists of eight GeoTIFF images, labeled like this:A1 B1 C1 D1 A2 B2 C2 D2 I would like to use these tiles for GeoServer to be served as WMS. Unfortunately, I don't know how to use multiple images as data source. 1) Can this be somehow done...

I am trying to convert my irregular spaced point data (xyz) to a DEM and then, to a raster (geotiff). Because of the irregular spacing I need a triangulation first, right (so, no spaces are in the final raster)? So the way is: XYZ -> Triangulate -> Interpolate To Raster. I have a lot of points...
