ArcMap can load lots of dataformats. The direct load of xls/xlsx is pretty nice as you have all the named sections beside the tables and don´t need to transform anything. There are some guidelines (directly copied from ArcGis resources) how the tables in Excel need to look like: Field names need to start with a letter. Field names should only include ...

You need to understand that there is no such thing as a QGIS Shapefile, A Shapefile is a shapefile regardless of what software was used to create it. According to ArcGIS Online Help: A shapefile is an Esri vector data storage format for storing the location, shape, and attributes of geographic features. It is stored as a set of related files and ...

You don't need arcpy for this. In Arcmap open the Attribute table click on the context menu and select Add Field Type in the name of your new field and make sure the field type is set to "Short Integer" and add a Default Vaule of 0 and click OK. This will add the new field to your attribute table. Note that this Default Value will not ...

Try "Select by Location" and set the trees as the Target layer. Set the buffer as the Source layer. Then, for the spatial selection method, use Are within the source layer feature or Are completely within the source layer feature. That should select all the points within the buffer. Now, you have three options: 1) In edit mode, open the 'Trees' ...

I am afraid you are missing the selection part with the feature layers. This is the workflow you are following: User opens a map document with some layers or add a feature class into the map as a layer. User selects a feature in a map layer. User runs your script. User gets the attributes of the selected feature printed. Here is where the problem is: ...

Create a field containing only the Year by slicing the existing field, and then symbolize using that field.

The results of zonal stat is one line per unique value in your raster, so this cannot be converted into a new raster without information about the position of each value. What you can do is joining your table with the original raster with zone values and then work on it. Make sure that you first "build raster attribute table" in order to do the join.

Usually join attribute has a one-to-one or a many-to-one relationship as shown in the documentation in Vince comment, however there is other solutions presented here you can try it, which is as follows: Open ArcToolbox. Go to "Data Management Tools". Click on "Layers and Table Views". Double click "Make Query Table". Select the correct "Input Tables" you ...

Yes it will, I see nothing in this process that would result in a vertical datum change.

This file should not have the extension *.asc as this would be very miss-leading. The *.asc extension is used for the simple (and very slow) ASCII grid format. The file contents you show above are what is typically referred to as an XYZ grid. It is a very verbose way of expressing a grid but can therefore also be read as a simple point cloud. As all of the ...

If you give your friend the shapefile, and it contains a suitable *.prj, then it should be usable in ArcMap but will need to be symbolized anew. The best thing will be to perform a test transfer of data and see if it works for you. If you are planning to share the shapefile and a layer definition file (*.qlr) to try and preserve its layer properties I would ...

The EPSG Geodetic Parameter Registry has two coordinate reference systems that match that well-known text. The first that I looked at was MGI 1901 / Balkans 7, EPSG:3909. The other one was Macedonia State Coordinate System Zone 7, EPSG:6316, which has the same definition. Using that information, I was able to find that the data is in Skopje, Macedonia. ...

You need to change the working directory for os and workspace. So, if your project directory was 'c:\testing', then you'd want to do something like this: mydir = r'c:\testing' os.chdir(mydir) arcpy.env.workspace = mydir Now when you make new files, that's the folder your new file will go.

Technically, you have to go into each shapefile separately to update it, but you could do it by running a single a Python program that loops through all the files in a directory and uses an update cursor to update the field in each one. Are your files all in a single directory? What is the name of the shared field? Anyway, the basic approach to the ...

(UPDATED - original answer wasn't what they were asking for) Per your comment below, you are asking where you can find/download data about income by zipcode. It's here: https://www.irs.gov/uac/SOI-Tax-Stats-Individual-Income-Tax-Statistics-2013-ZIP-Code-Data-(SOI)

You need to use Spatial Join from ArcToolbox: ArcToolbox -> Analysis Tools -> Overlay -> Spatial Join Then input the first polygon in the Target Feature and second polygon as Join Feature. In the Match Option use intersect (default) if you only need the PIN number without considering to be exactly inside the first polygon.

Whenever you handle large amounts of raster-data it is comfortable to use a raster-catalog. The raster-catalog is an option of the file-geodatabase format. You can create the database via right-clicking on your folder in the catalog-window where you want to have the database, just choose "new" -"file-geodatabase". Then choose "new" - "raster-catalog". The ...

Firstly you'll need a spatial layer showing the state boundaries. A rough dataset is included with ArcGIS and is located at C:\Program Files (x86)\ArcGIS\Desktop10.2\TemplateData\TemplateData.gdb (or a similar path on your computer). You'll need to make some changes to your Excel file before you add it to ArcMap. Note that the column names cannot have ...

The link you post it brings me to a Catalogue Service where the metadata of a cartographic resource is located. This kind of Services are useful to share the information about geographic resources like who's the owner of the data, the extension, where you can download it or buy it, contact point and more other INSPIRE parameters. The XML download option of ...

The graphics card is rarely an issue when experiencing performance problems with ArcGIS (i.e. unless you are doing heavy 3-D visualizations). In fact, I successfully run a version of ArcGIS on a server that does not have a graphics card. Instead, I recommend focusing your attention on increasing 1) the RAM and 2) disk read/write speed by installing a solid ...

Possible solution to 'automate' your process Add shapefile to mxd, open it's table and click field calculator, Python Apply modified version of this: [!thisField!, 7][!thisField!==50] To modify expression: Replace left pair by your field name, and new value Right part is your condition, replace it by field name and value to be replaced Try it first ...

Add field type long RoadId to roads and populate it with sequential number, e.g. [FID] Spatially join mammals to roads (closest), output – shapefile Spatially join traffic count to roads (closest), output – shapefile. Make it first layer in table of content. Add field TRAFFIC to both shapefiles, populate it using volume for joined traffic Run this field ...

Thankfully it was just a stupid mistake. What happened was I had created a new Map Document to work with this particular polygon feature. When creating this new map document, I forgot to change the Coordinate system to use Feet as the Map Unit of measurement. So, when I was entering my Direction/Length, it was looking for Decimal Degrees and I was feeding ...

When you publish the hosted feature service, you specify the maximum number of records that can be returned from the service. This is done under the Parameters - Max Record Count property (in the Service Editor wizard), just as you did. I have noticed that changing this doesn't always getting through. I had to re-publish the service specifying before ...

You could just use the unique values in the Symbology tab, select the range of values that you want to categorise (click the first value, hold down shift and then select the range of values), right mouse click and select group values. Then in the label column, assign it the new catagory label e.g 2-3

You could try adding the Rename Tool to the right of your output raster(s). As your input to the Rename Tool, connect your output raster(s). For the output data parameter in the Rename Tool, you should input the file name you desire. In your case, something to the effect of "C:\temp\HogHab1_%Value%" or "C:\temp\ModRas1_%Value%" respectively. What the ...
