I had posted this on the ArcGIS forums, but thought I may get some further input here. Having issues acquiring the appropriate input and erase features during the iteration process. Please see below linked ModelBuilder image. The model is currently not functional as the inner nested model...

I want to use a cell count of an integer raster as a variable in Arcgis 10 ModelBuilder (and later in a python script), but can't seem to find how to access this information. Is there a (python) function that will return a cell count for a particular value? eg. something like count([raster]...

In this video I use ArcMap 10.1 with a 4 band Aerial Photo (RGBiR) to calculate the Normalized Difference Vegetation Index (NDVI), a graphical indicator that can be used to analyze remote sensing measurements to assess whether the target being observed contains live green vegetation or not. I...

I'm using gSimplify (rgeos package) to simplify the geometries of a shapefile.The funcion works good, but now I can't write the output in a new shapefile.I tried some ways: writeOGR(simplyshape, file, driver="ESRI Shapefile",layer = 'test')I get: obj must be a SpatialPointsDataFrame...

How is it possible to embed content — like YouTube-Videos, Twitter-Tweets, Facebook-Posts, Instagram-Photos or andy other kind of embeds —*into a InfoWindow in CartoDB? In my Dataset there is a row with the embed-code (iframe, script etc.) and I included the field into the infowindow via the...

I built my own map canvas inside a plugin in QGIS and I want to add two layers (one by one) in order to overlay the two. I have this code: fileCI = "....\plugins\teste\test.shp"fileInfo = QFileInfo(fileCI)layer = QgsVectorLayer(fileCI, fileInfo.baseName(), "ogr")if not layer.isValid()...

I have two shapefile layers in a Qgis project that have problems with zooming. One is a line I copied/pasted in a new layer from a set of height contours and the other one is a polygon layer I created by dissolving all features in another layer. In both cases, the layers won't display unless...

I'm looking to do analysis on cities throughout the world. I'm using WorldPop, LandScan and MODIS data to gain urban extent and population density maps. I would like to extract areas which have a population size above 100,000. At the moment I think I may have to manually go through each city and...

I cannot change "Layer display level" of category in OSM Data. I would like to have "tertiary" roads under the "primary" roads. There is also a problem with displaying second level of line symbol. Everything works great on vector lines with category attribute drawn by me. How to fix it...

I need to find the amount of public transport stops in a distance of 400m of my point input features. In the layer properties I changed under 'Analysis Settings' to Default Breaks: 400m and under 'Network Locations' the Search Tolerance to 100m. On a small rectangular test area everything...

I was tracking tourist's movement patterns in a city with GPS and I would like to know the speed of all participants (60). The data were recorded and saved in gpx files, so in order to open it and work with it in QGIS, I converted the tracks from gpx to KML and SHP. I would like to know the...

I tried to solve the following issue by myself but without success. On the one hand I have a raster file which is the result of the processing "shapes to grid" tool. On the other hand I have a boundary vector file. Now I wanted to use the zonal statistic tool via processing toolbox. But the...

I'm want to generate wfs and wms from postgis database. To do this i want to make a scripting with python (or with another language) to store my shapefile on geoserver and then deploy services automatically. Is there any good approach to follow? OWSlib could be one? And what about geoscripting...

Similar to this post: SAGA algorithms don't work in QGIS 2.8 except the fact that SAGA does not appear at all in the Processing Toolbox: As a check, I used the Python Console with the following code to see if any SAGA tools are available (which they're not): import processing...

Most of the time I have to reload all the layers when opening a QGIS project file (.qgs), which is pretty annoying. I didn't change the name of the files and folders and I didn't change the folder structure. What am I doing wrong? I use QGIS 2.8 on OSX Yosemite 10.10.3...

بسم الله الرحمن الرحيم تنقسم عملية التسوية ( الميزانية ) إلى نوعين رئيسيين : تسوية غير مباشرة – تسوية مباشرة . أولاً- التسوية غير المباشرة : وفيها يتم قياس المنسوب بطريقة غير مباشرة وتعد دقة القياسات فيها دقة منخفضة ، ومن الأمثلة عليها : 1. التسوية البارومترية : وتعتمد على مبدأ أن الضغط الجوي...
