In the documentation, it is alluded to that you cannot edit data in a SQLite database from ArcMap: You can connect from ArcGIS to an SQLite database to create maps and perform spatial analysis on your data. However, the only place this appears to be explicitly stated by Esri is in the ArcGIS Discussion Forum: Yes; you cannot edit data in a SQLite ...

CSV layers cannot be edited. You have to save to a different format, e.g. Shapefile, before you can start editing.

Do you have the ESRI FGDB API set up so that ogr can access file geodatabases? If so, you can open the file geodatabase layers in QGIS 2.0 and use the database manager to import each layer into a PostGIS database. If you don't have the API you can't get to the data in the file geodatabase. It's easy to install on windows, just use the OSGeo4W installer. ...

I think what you are actually trying/wanting to do is create subtypes as shown in the graphic here. You can then apply domains by subtype. In your example type would be a domain of plastic and metal, which in turn would be subtypes, and then metal would have a domain of yes/no for rusted, but plastic would have a domain of N/A or whatever other option. ...

This is possible. But for QGIS to support this type dynamic change when editing data, the data has to have a backend to support that like a RDBMS. If using PostgreSQL that has PostGIS enabled, you could create a new VIEW to facilitate the requirements of the JOIN. Then when you add a new feature to your source table (the geometries) or the view, then the ...

QGIS (like any decent GIS) has a vast slew of vector creation and editing tools. These tools work well with most OGR vector formats but there are some limitation for some formats. Unfortunately, KML is one such format. You will be able to do a lot of the editing tasks on a KML directly such as add new features and use some of the Editing and Advanced ...

When moving your features manually, right-click your layer -> Edit Features -> Start editing (if you can click continue on all messages appearing you are good). Then you select the feature(s) that you want to move, and move them with the arrow from the Editor toolbar (regular arrow won't do it!). You can resize polygons with the Buffer function on the ...

You can use Advanced Editing toolbar with Construct Polygons tool for that (available to ArcGIS for Desktop Standard and ArcGIS for Desktop Advanced only). On the picture to the right, the selected lines that form a triangle are used for constructing a polygon yet an existing large polygon is taken into account and just two small triangles are created. It ...

You open the table in ArcMap by adding the table or layer to the table of contents, right click on the layer and select open attribute table (if it's a table look for it in data view). Then you can use field calculator or edit the cells individually by clicking in them and entering data. One more important thing, to edit cells in a table you must be ...

There is a plugin for QGIS 1.8: TraceDigitize Author's tip: "Use ctrl-Key to trace, backspace to delete, left mouse click to set a normal vertex and right mouse click to finish. Uses the snapping options, which may be changed during digitizing (Consider opening the snapping option as dock widget)"

You're using the wrong tool for filling the hole: You're using the "Delete Ring" tool, but you should be using "Add Feature". "Delete Ring" is used for deleting an interior ring of a single polygon feature (like the hole in a donut polygon). However, all your features are simple polygons consisting of only an exterior ring, so when you try to draw a large ...

I assume you are wanting to join two line segments into one line. This is how I did it ... Enable editing. Turn on snapping ( Settings -> Snapping Options ... ) Select the node node tool. Double click close to the end of one of the lines to add a node. Drag the node at the end to snap onto the the end of the other line Select both lines Merge their ...

My solution to this problem was to use the extensions available for the Arcpy Addin Toolbar. I added an extension that listens for an edit session to begin or end. I have all of my buttons on the bar set to :self.enable = False" to start with and then these buttons are then either enable or disabled by starting or stop an edit session. class ...

I am pretty sure it's a part of the Production Mapping extension. http://resources.arcgis.com/en/help/main/10.1/index.html#//010300000214000000 This is not a free extention. (approx $9000) I don't think there is a free trial for this one ethier altough you might be able to contact your ESRI rep and see what you can do. At least it is not listed as the trial ...

The Multipart To Singlepart tool explodes multipart features, creating a new feature class of single part features.

Unfortunately no. Validate Features is a really simple tool for finding out if you have any unvalid features in your selection. There is no way to tell why these features are invalid in batch mode. What you can get out-of-the-box is to select all your features in the editing session > Editor > Validate Features. You will get only unvalid features in the ...

To answer your question, no, there is no 'fill' tool like you're thinking, and it's actually a lot more complicated than it sounds. Those types of tools work on basically 2D raster data and a 'fill by flood' operational concept. That gets more complicated in a vector environment where you have to start considering vertices and not just overlapping lines. ...

First enable the editing toolbar --> Customize --> Toolbars --> Editor or right click any grey area and add the editor there. The feature template menu can be found by entering an edit session clicking on "Create Features" (the far right menu) and then clicking the right most menu under the create features panel (see attached screenshot) Here is some ...

ArcGIS is set up to edit only versioned data in ArcSDE by default. You can change this behavior in if you need to edit SDE data that is unversioned. See the documentation for v10.0 at Configuring an ArcMap edit session to perform nonversioned edits

From the context menu while digitizing a new line I would use Absolute X,Y to enter the coordinates of the start vertex and Direction/Length to do the second (and last) vertex 120 degrees and 500 metres away. You then have a selected line which is ready for Construct Points which "creates new point features at intervals along a selected line".

EDIT This solution is correct for removing an interior ring (conventionally known as a 'hole'). However, until we saw the OP's screenshots, the situation was not clear. The OP does not have an interior ring, so Jake's solution is the correct one in that use-case. I'll leave this answer here in case future readers have the same confusion over enclosed ...

Quoting the shapefile specification: A polygon consists of one or more rings. A ring is a connected sequence of four or more points that form a closed, non-self-intersecting loop. A polygon may contain multiple outer rings. The order of vertices or orientation for a ring indicates which side of the ring is the interior of the polygon. The ...

To create multipart polygons or donut polygons you have to use the command Finish Part. For a donut polygon: draw a new polygon without finishing the sketch right-click and click Finish Part draw new polygon inside your first polygon to create a hole finish the sketch. For a multipart polygon: draw a new polygon without finishing the sketch ...

If you are trying to edit a shapefile you will have to have exclusive access to the file (no other users accessing it) in order to get the lock for editing. You can see this question about how to "kick them off". Alternatively, you could just ask your co workers to stop using the shapefile while you edit.

You could try Hawth's Tools: http://www.spatialecology.com/htools/rndsel.php Note that the existing selection is not honored so you would have to make a feature layer from the existing selection first.

There is also an earlier Select features at random script from Stephen Lead available for ArcGIS Desktop. Although written, I think, for ArcGIS 9.x, and last modified in 2008, I used it in about 2010 at 10.0, and it still worked well.

I prefer do this kind of stuff at database level, to ensure the integrity of the data. If you make some custom plugin in your GIS to handle it, any user with database access can make changes without using your plugin. I see two option to implement it in the database, where the best option depends on your user cases: Triggers, that tracks the changes to ...

You cannot import the "relationship classes" because the ESRI FileGDB API can't read those unfortunately. And the GDAL driver relies on the ESRI FileGDB API to get read/write functionality for a FileGDB. But you can convert the FileGDB you have, only the feature classes and tables, to a PostgreSQL database with PostGIS. The PostgreSQL database with the ...

Compaction reorders records and frees up space, compression converts the geodatabase to read-only format. As Vince has commented, the only way to know if it has a beneficial effect is to try it. If your FGDB is heavily used with lots of additions and deletions, then compacting may well provide a benefit to performance. If you only ever add data then it may ...
