We tried to use postgresql+postgis to save our spatial data with points/lines/polygons. Though the postgresql have a built-in full-text search engine, we have to use lucene for some reasons, and though the Lucene have a spatial engine, it does not support the line/polygon interception. :(...

I find example to set map extent that works ok in ArcMap via.. mxd = arcpy.mapping.MapDocument("CURRENT")..df = arcpy.mapping.ListDataFrames(mxd)[0]newExtent = df.extentnewExtent.XMin, newExtent.YMin = newExtent.XMin+100, newExtent.YMinnewExtent.XMax, newExtent.YMax = newExtent.XMax+1000.0...

I have configured my config.yaml to include the dsn match as host: aerial.openstreetmap.org.za . I can see the aerial photos in my client app and using wms inspector i can confirm the dsn is indeed aerial.openstreetmap.org.za. How can I get to print my map with the open street aerial background...

I am trying to build a Geo BI dashboard using Open Source GIS. I have gone through posts and presentations that suggest using GeoKettle as the spatial ETL tool, GeoMondrian as SOLAP Server, PostgreSql with PostGIS for my data warehouse and SOLAPLayers or GeoBIExt as SOLAP Client, but I cannot...

I want to migrate .NET application from arcobjects to Arc GIS Pro SDK.As I understand some operations such as creating tables and feature classes, creating and modifying fields need to be performed using the Geoprocessing API in Arc GIS Pro SDK. Where can I find full list of such operations or...

Greetings and respect to all my dear friends ... I want to examine a phenomenon with a scale of 1x1 meter through remote measuring. I know I can do that by 1. Using high spatial resolution images or 2. by combining two images with low or mediocre spatial resolution, I can upgrade the spatial...

I have seen that people already had issues about overlapping class boundaries with the classification of graduated vector data. I am wondering if there is somewhere written in the documentation if the upper class boundary contains the stated value or if the class ends "just before" the stated...

I'm new to StackExchange and to remote sensing. I am working with MOD13Q1 250m 16-day MVCs. My goal is to use NDVI time-series to classify cropping pattern and crop type, then link this data to water issues and rainfall. I am working with ENVI 5.1, which is also new to me. I have used the...

Datums! Coordinate systems! Map projections! Topologies! Spatial applications are a nebulous, daunting concept to most Pythonistas. This talk is a gentle introduction into the concepts, terminology and tools to demystify the world of t أكثر...

I've found method X of calculating snow cover in paper Y but the technicalities are not fully explained. How can it be done using the software I have" (ENVI? ERDAS?) – أكثر...

I had setup the cartodb locally in my machine following this tutorial https://github.com/danseely/cartodb-install/blob/master/DEV-INSTALLATION.mdEverything is installed perfectly i can visualize a data in my local account,but when i try to import a dataset it's showing error so i created...

I want to calculate Snow cover. i have MOD10A1,MOD10A2 and Cloud Mask, but i don't know how to use them,i read many papers but every body write not clear about the procedure how to use them. MOD10A1 and MOD10A2 have no bands then how they calculate Normalized difference snow index? also how to...

I have a collection of rasters (all in separate geodatabases) that I am trying to put into a MOSAIC using a python script. I have a bunch of these to make so I was thinking that the easiest way to do it would be to create a .lyr file containing all the rasters I want to add and then have a...

I am writing a python script tool for ArcGIS that applies a classification to a feature layer (updating a curent field) with the appropriate recognition of other attributes, and set result field (as text) according to the classification.Hear is what I have so far: أكثر...

Like feature layers have the queryAttachmentInfos() method to fetch attachment info, is there something like this to fetch attachment info from a map service (ArcGISDynamicMapServiceLayer)? My app flow is as follows query the map service based on some user defined criteria set info templates...

my question is: is there any easy way to resample 30 meter NDVI from Landsat 8 images to 5 Metres. I use raster to point and the interpolation of point to raster using Krigin method. I know that it may not be a proper way of getting 5 m NDVI but for the purpose of demonstration I need to do...

I have various Landsat 8 images and try to do cloud Masking, there are a lot of materials regarding Cloud Masking but not particular for ArcGIS, I would appreciate if anybody explain briefly what steps do I need to do so. Another Question: when we have NDVI ready image of Landsat 8, are they...

For modeling purposes, I need to use two raster maps that contain exactly the same number of rows and columns. How should I process my maps to obtain this result? For now, my maps don't have the same number of rows and columns... Thanks a lot! أكثر...
