I had similar problems with an earlier version of QGIS, and solved the problem by storing my data in spatialite databases. The shapefiles I used before seamed to have reached a critical size (not in Gigabyte, but number of features). Especially point shapefiles, like bus stops, which tend to grow rapidly.

Boundless has a tool called GeoGig: http://geogig.org/ Users are able to import raw geospatial data (currently from Shapefiles, PostGIS or SpatiaLite) in to a repository where every change to the data is tracked. These changes can be viewed in a history, reverted to older versions, branched in to sandboxed areas, merged back in, and pushed to ...

You can "stream vertices," which does not simplify on completion. Full instructions here. In short, after you've placed the first vertex, right-click and enable streaming. Vertices will be placed at intervals according to the streaming tolerance set in Editor options.

Do you try to edit event layer created from XY coordinates excelsheet? Try first to export the event layer to shapefile (or feature class into geodatabase).

Unfortunately you cannot switch the auto-simplification off. "The freehand drawing line is automatically smoothed into Bézier curves." http://resources.arcgis.com/en/help/main/10.2/index.html#//01m700000067000000 Workround you can convert your feature to a cartographic representation and you will be able to use the freehand tools without the ...

From your screenshot it looks like you're editing a fiber network, so I assume you're using a geometric network. You need to add the Geometric Network Editing toolbar Highlight the line you want to disconnect from the geometric network and press the second button from the left (Disconnect). You can only disconnect one feature at a time. After you move it ...

Sometimes feature classes that participate in geometric networks or composite relationship classes in geodatabases tend to move and delete together during editing. Maybe check to see if your lines participate in a geometric network, or a composite relationship class? If so, try deleting the geometric network or the relationship class in question and attempt ...

Give this a read - Editing The ArcGIS Web APIs provide simple feature editing. The features must come from an ArcSDE geodatabase. This geodatabase can be licensed for either workgroup or enterprise use and does not have to be versioned.

In my QGIS 2.4.0, the "delete ring" doesn't work when I have "on the fly" CRS transformation turned on.

Firstly you should check your all files location and make sure that all files are in .shp format and also remember one thing that you can not edit any excel sheet without converting it in to .shp file. if again you face such a similar problem then create a GDB and export all layers in GDB,after that you can edit it and also make sure your Arcmap should be in ...

If I understand your question correctly, it sounds like want to have three points created for each row in your table (one for each of the three fields). When ArcMap imports a table like this, it will only create one point feature for each row in your table. So if you want it to create three points per row (one for each of your fields given for each ...

Export your table into a .gdb or as a .dbf, the ObjectID field will be added, and you can commence editing. If it's a feature class, similarly export into a .gdb or as a shapefile

Yes, you will be able to query and edit related records from Javascript, assuming the Server data has been set up for this of course. The pros and cons of actually relating tables will depend a lot on how you plan to use and maintain the data beyond GIS. I recommend reading the Esri article on joining and relating tables before deciding if it's the right ...

Try editing your table so the field names don't contain spaces, special characters etc. That's what causes the error on export to shape, and may be the root of some of the other issues you have as well...

In the symbology tab, go to Add Values, then click the Complete List button. All the values that are not currently symbolized should appear. Highlight the new values and hit OK to add them.

I remembered doing this for a project a while ago, but it took me a while to re-find the menu! In the Editor toolbar, open up the Options dialog and go to the Units tab. Enter a Distance Factor that converts from units you have (e.g. feet) to your projection units (e.g. meters). See About distance units and editing for some common conversion factors. ...

Right clic the Feature class in ArcCatalog and go to the Properties. In the Feature Extent tab, clic on Recalculate. And voilà! I'm using ArcGIS 10.2.1

Here is a method using arcpy geometry objects. The script creates a rotated hull rectangle around each polygon, splits it into plots, and clips the plots to the original polygon. As Aaron mentions, you could likely achieve this with the fishnet tool, but I could not figure out how to (in Step #2) "use logic to find the ordinal coords" for rotated polygons. ...

I had an issue where the editor would not even select a certain point feature. I would have to select it with the "Select Feature" tool and then it could be moved but it would still not snap to the line feature. Not sure why this worked but I turned on a different point feature and was able to select it with the editor and could snap it. When I went back ...

The coordinates in the attribute table are numeric values that are not linked with the geometry. If you want to create a large number of points with exact coordinates, I suggest that you create a table with those coordinates, then use create an XY table event that you can merge with your existing shapefile. If you need to move just a few points, then ...

The location coordinates of your feature are stored in a geometry/shape field in the attribute table, not a text readable field you can adjust. You can store the coordinates as attributes, but they won't actually control where the point is. There are a few ways to address this: First, you could just make a table/spreadsheet/csv of your coordinate pairs. ...

Since you're not worried about simultaneous edits on features, I'd say that in theory you have nothing to worry about. The main danger w/ QGIS is that simultaneous editors can stomp on each other's edits without noticing ("last edit wins"). For data under active editing with multiple users you might want to at least keep track of history, which you can do ...

You could automate this approach with Python using the Create Fishnet (Data Management) tool. You can extract all of the pieces of the puzzle to do this analysis with python and then simply plug the pieces into the fishnet function. You need to start by iterating over all of the section polygons. Otherwise, you will get one large fishnet covering the ...
