I am looking for a mobile app/interface for field data collection and mobile editing of GIS data that relies/syncs back to some type of GIS server or database. I am aware of Fulcrum and AmigoCloud, but those are third party. I have yet to roll out a GIS server simply for this reason, I still...

I have a GeoJSON from NaturalEarth for world state boundaries and I want to display it with only without backgroung. But also, I want to add a OSM layer as another baselayer option. The code I am using is the following one, but when I check it, as OSM is in another projection, the center map...

more of a broad question here: I'm trying to take a huge amount of spatial data for a specific 200,000 acre area, collected over 15 years dating back to 2000, and organize it. The data layers relate to wildfires, habitat rehabilitation efforts, biology, vegetation etc. The goal is that for...

We are able to Delete feature from openlayer and it is successfully deleting that from spatial table also. However we are unsuccessful doing add/edit on openlayer and save the same in Spatial table. Getting the below exception while saving the data to spatial table. ORA-13364: Layer...

So I downloaded some data from the 2011 UK Census and I want to add it as a layer on my basemap. I couldn't see it on the map although it was in the Contents tab in arcmap, so I zoomed out to full view and saw that it was way off. There must be a mis-match in coordinate systems between the...

I would like to buffer features into an existing FC within a GDB, similar to when buffering during an edit session by using the Buffer command in the Editor menu, not the Buffer geoprocess which creates a new FC. Is there a way to do this in model builder? I can only find the buffering...

I have a feature class that contains 131000 records. One of its fields (which was originally joined from a table) only has three possible values: null, 0, and 1. I have been trying to select the features that have a null value in this field, but each time I attempt to do so, it crashes. My...

I am running PostGIS on an Ubuntu server. I am able to add the Topology extension via CREATE EXTENSION, but when I try to use it as anything other than an admin I am denied permission. I ran GRANT USAGE ON SCHEMA topology TO public, as suggested in this chain. When I run CreateTopology() I get...

Currently, we are able to export a layer with labels(these are one's which are coming from stylesheet sld:label) to pdf. But our requirement is, user should have an option where he dynamically add some text(this text should not be saved) on a layer and export that to pdf.So, that text should...

What is the best way to determine if a polyline (not just the vertices) intersect a polygon? Or checking if the polygon contains any of the polyline? I am checking within a function where my polyline is an array of points like below. var myPoints=[[42.414649077488, -71.13123893737793]...

When I run the Add XY Coordinates tool, I end up with these XY values. At first I thought this might be a projection issue. I adjusted the projection in arccatalog to make sure it was the same, but still end up with the crazy big values in the POINT_X and POINT_Y columns. Any idea what might be...

Bonjour à tous ! Cela fait un moment que je travaille avec des cartes grâce au format geoJSON et uMap. J'importe des fichiers correspondants à des cantons français (regroupés par même code postal) seulement je dessine toujours manuellement les "contours" de mes régions. Je me suis dis...

I am seeking suggestion on something I am trying to solve in ArcGIS. Please look at the above attribute table as an example. I am trying to reduce the attribute table by var1 (i.e. the polygons with similar var1 values will be merged) and calculate the corresponding values for var2, var3 and...

Good afternoon,I'm trying to make a search engine in OpenLayers3 by Geoserver features and WFS. To do this you should use a CQL filter? this is my connection code if geoserver mediantes OL3 would be so kind as to show me an example of CQL from Openlayers. thank you very much...
