Your code looks to do a lot of unnecessary things. For instance, you iterate over filed list, but never use variables fl or fld. So here is code that could do what you need from my understanding. It first gather all the place_name variables and put it in a dictionary and after, iterate thought the second feature class and update the values. import arcpy ...
If your editing situation is conditional you may use a CASE expression within field calculator: CASE expression A conditional expression that can be used to evaluate multiple expressions and return a result. Syntax: CASE WHEN condition THEN result [ ...n ] [ ELSE result ] END Example: CASE WHEN "mycolumn" = ...
OSGeo4W shell solution IMHO the simplest way to extract the attribute table properties (schema) consists into opening the OSGeo4W shell ('cause you're on win os), change directory to your data folder and simply type something like: ogrinfo -so inputLayerName.shp inputLayerName It will show you the summary information like projection, schema, feature ...
Just open the .dbf file in Libreoffice Calc or Excel just save it as a new file. I saved over it once and the shapefile was no good.
[Posted earlier as an "edit" to my own question. Per Sorin's advice, I'm changing this to an answer instead of an edit.] I think I may have solved it. I used a percent sign ( % ) as a "wild card" along with the LIKE operator, and it looks like I got the expected search results. Example 1: In a roads shapefile layer, "FULLNAME" LIKE '%68%' produced a ...
Try some of the DBF metadata extractors available. Most of them support command line mode, so multiple metadata extraction can be run in batch. http://geology.usgs.gov/tools/metadata/tools/doc/dbfmeta.html http://sco.wisc.edu/wisclinc/metatool/dbfmeta.htm
If I understand your question correctly, I run something similar on occasion for stormwater lines. It involves extracting depths at each endpoint and adding them to the table of the lines. What you can do is create your own Unique ID's based off of the XY coordinates of both sources and then use those to join the tables together. You would end up doing two ...
Following on the .dbf theme have you looked for .dbf comparers directly? I haven't found a free solution immediately, but something like: dbfCompare
Shapefiles hold their attributes in .dbf files, can you not just open the .dbf file directly in a program like libreoffice calc and then print from there? If you don't have too many files this should work. Another option would be to write a python script that prints out (to the console) the attributes of features directly, or even compares them for you. You ...
You can also use the column filter of the attribute table. It works default as a 'like' expression without the % wild card. Result when typing a:
You may want to try renaming the following fields: ID, Date_Time, x, y, and label.1. Just a guess, but they could be reserved names in the case of the first 4, and ArcMap may not like the '.' in the final field name.
If you have a single band raster, then the problem comes from the other constraint : integer type. Your porosity value is probably float. To solve your problem, you need to build a new raster dataset using "map algebra" (assuming you have the spatial analyst extension). Another solution is to reclassify your raster so that you can build an attribute table, ...
Not knowing the history of this map it is not possible to be certain, but from the description of what solved it, I would say that you were seeing Graphic Text that was created in your map at some point in time. There is an Online Hep Page entitled Essential annotation and graphic text concepts that may be worth reviewing if you want to know more about ...
The text you see is the result of Paste operation. The most likely reason for that is that you had either created a report in ArcMap or copied rows from Attribute table by using Copy (or just Ctrl-C shortcut). This piece of data was stored in your operation system clipboard and when you were trying to copy/paste a layer in the table of contents or a feature, ...
