You are probably going to want to find either a good programmer or start reading and figuring out JS. The basic way to do this would be to either find the feature being snapped to (might be a property of the event) or run a spatial query from the feature you added to find the nearest feature in the other layer (assume distance = 0). I do this in a .NET ...

Fixed. The problem was is no primary key. In pgAdmin do this request. ALTER TABLE tableName ADD PRIMARY KEY (id); Example for planet_osm_line table and setting osm_id column ,as primary key : ALTER TABLE planet_osm_line ADD PRIMARY KEY (osm_id); untill osm_id is unique.

The error sound and clear. You should refresh a version outside of an edit session. The RefreshVersion method refreshes the version to correspond with the database state the version references. For example, if a second application is editing the verison and saves their changes, you need to call the RefreshVersion method to see the latest ...

To enable many editors to work on a single dataset or group of datasets, you can use geodatabase versioning. Have a read of the related ArcGIS help article for a complete how-to. In a nutshell, you'll be able to have multiple users editing data, and edits which are submitted to the geodatabase can be moderated if need be.

I think this is a primary key issue - does your table have one and is it recognized when you view the table through PGAdmin? I had this same problem, but re-loaded the layer with a primary key field called ID (arbitrary) and all my edit tools are now active on the toolbar. EDIT Using SQL you can add an OID column of 'serial' data type and create a ...

Have you tried using the Offline plugin for QGIS? This syncs your PostGIS database to SpatiaLite and then syncs it back. https://docs.qgis.org/2.2/en/docs/user_manual/plugins/plugins_offline_editing.html If you need something custom, then go Spatialite; QGIS can edit it and you can setup triggers, views, querys etc that you have in your PostGIS database ...

Whenever you start talking about "stretching" features in FME, two transformers comes to mind - the AffineWarper and the RubberSheeter. Affine Warper Performs warping operations on the spatial coordinates of features. It is used to adjust a set of observed features so they more closely match some set of reference features. This transformer computes ...

Wow! Never thought it is that complicated. To pay for my arrogance I wrote a script that handles this. Script assumes that 1st layer in TOC is target polyline layer. Tool parameters script gets selection and populates one and the only script parameter (Type Long, MultiValue = Yes). Validation script: def initializeParameters(self): """Refine the ...

If you create a single polyline feature from the lines shown, a multipart feature will always be created. This rule concerning self-intersecting features is built-in to the Esri specifications for a polyline and cannot be overridden. Polygons are made from closed polylines and polygons must force a multi-part polyline feature at self-intersections to draw ...

In the dialog box asking you which feature's attributes to keep, uncheck the "Merge into a single COGO line" box.

The feature that you need was added into QGIS six years ago based on this ticket http://hub.qgis.org/issues/748 The trick you must to do is to drag a rectangle around the end/start nodes for selecting them both so that you can move them together. However, it you delete the selected nodes the result will be unexpected and surely not what you want. For ...

There are two issues when editing with different coordinate systems in ArcGIS. The first issue is the one that you probably have in mind: if your coordinate systems do not use the same datum, ArcGIS might reproject your data on the fly without transforming the geographic coordiantes from one datum to the other datum. You can check in the properties of your ...

tracing doesn't use snapping. there are several ways around this. the trace will follow to the side your cursor is on (this can be used in simple conditions). you can use the trace selected. (by selecting the layer you want to trace) replace geometry

To select multiple features in ArcGIS 10.1 you can open up the feature layer's attributes and choose select by attribute. This will allow you to filter the selection by using certain fields to mark the features to be deleted. Along with that you can invert selection if you are able to easily select all of the features that you want to keep and then switch it ...

Try changing the selection mode in ArcMap to Add To Current Selection. Then you can select multiple features. See the link here for a discussion: http://resources.arcgis.com/en/help/main/10.1/index.html#//00s50000000w000000

It sounds like you'll need to source some more data. There's no way to expand your DEM or Contours without actually finding data. I'd suggest that you look into your local, regional, or national government spatial agencies. Perhaps search for open data repositories in your area. If all else fails, there's a global elevation model at around 30 m resolution ...
