You need to finish the polygon's construction with double click, right-click>Finish Sketch or F2 before saving edits.

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. ...

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. ...

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. ...

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 ...

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 ...

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. ...

Reiterating the comments as an answer for the convenience of others: Always make sure that each layer has a unique shapefile associated with it, otherwise data losses will be likely if more than one layer is based on the same shapefile and you edit its attributes.

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 ...

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. ...

The reason you cannot edit these layers is because it is not a file. It is a map service. What you are seeing is a web service. A web service is data that is hosted on a server elsewhere, that is not your computer. Your computer is going out and getting the data live from OLIVER when you look at it in ArcMap. In this case the data you want to edit is ...

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 ...

If you comment out the Store call, you should be good: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//0025000007wv000000 Store should not be called inside of edit events, such as OnCreateFeature, OnChangeFeature or OnDeleteFeature. Even if you are modifying the geometry or other field values, Store will be called once the ...

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 ...

This is not possible with WMS. WFS gives the data itself (READ only), and WFS-T is a transactional extension of WFS that allows you to CREATE/UPDATE/DELETE data through the WFS protocol. In your case, for what you need, you can't use WMS / GetFeatureInfo but you need WFS-T or to use a different approach like JDBC to edit the content of your postgis tables.

You can achieve this using the Construct Points tool while in edit mode. If you need to do this to multiple features, you could use the Densify tool, then use the Feature Vertices to Points. Keep in mind that this assumes you currently have lines, and not polylines, because ALL vertices (even one's not at your specified densify distance) will also become ...

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. ...

I'd recommend looking into GeoGit. I believe it has just the functionality that you're looking for.

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 ...

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 ...

The most simple workaround to this problem is to create a buffer around your line, then you convert the buffer into a line ("Feature to line" using both the buffers and the original lines) and finally you run the "extend" tool (Info/advanced licence needed for feature to line, and Editor/standard licence needed for extend, but there are free solutions for ...

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 ...
