From what I understand of your question it sounds like you need to join two tables together dependent on a common feature (i.e. rowID). Try using the Spatial Query plugin. Go to Plugins > Manage and Install Plugins... and search for 'Spatial Query Plugin' install that, if you haven't got it installed already. Once Installed go to Vector > Spatial Query > ...
You appear to be confusing "attributes" and "values". By selecting the [Data Type] as "date" you are informing ArcGIS that this field or column will contain dates. You have not told ArcGIS what those dates are. If you were to add another field or column and set the [Data Type] as "text" would you expect Arc to populate it with the word "text"? The [Data ...
A possible solution to your problem is to do the following: Create a Personal Geodatabase file (.mdb) in a directory Load the DWG file into ArcMap Right-click the layer that you want to export a feature class -> go to Data -> Export data -> Under Save as type: choose File and Personal Geodatabase Classes Navigate to the personal Geodatabase file that you ...
You need to use the Field Calculator or Calculate Field tool to calculate your new field equal to your old field. Make sure that your new field is defined the same as the old field. Otherwise it cannot be considered to be a copy.
If you are working with a shapefile attribute table, you can export the shapefile with its joined table to a new shapefile, and the joined table will become permanent inside the new shapefile's attribute table. Next, add a new field of type integer and use the Field Calculator. Then you can write the following python code following Calculate Field examples, ...
Apologies for being vague, but this is a similar workflow i've used in ArcGIS and I'm sure it can translate to QGIS: Create a uniqueid for your Lakes Select by location Calculate code for Lakes Join uniqueid, code in new shapefile with Lakes uniqueid layer Export new Lakes Layer, delete uniqueid column Or create a python script/tool that will: Iterate ...
What you could do 'select by location', selecting only those lakes that fall within a county. Then update 'code' with the county code. I'm sure python could make this a lot faster.
If you do not have qgis installed, still you can do it online. Point2Poly You need to browse your csv file and select the latitude and longitude fields, then generate the shapefile.
You could easily achieve this with modelbuilder: use a featureclass iterator to iterate over your shapefiles, this feeds into an add field, then calculate tool using inline substitution from a parse path tool to store the file name. Once you have run that you can run a merge tool bring them altogether into a single dataset. Basically read the help file and ...
Depending on what attributes you have in your states you can join them based on location using QGIS. The tool can be found at "Vector"-"Data Management"-"Join attributes based on location". Your target will be your shp1. It then should bring you all attributes from your states.
