Under the Spatial Statistics Tools, under Utilities, there is a tool called Export Feature Attribute to ASCII.
This tool will write out a .dbf Attribute Table to ASCII, thereby negating my previous bitching about it. You can choose which columns to write out, and you can choose the delimiter.
Great, Way to make me feel dumb, arc. I can still complain that this tool is hidden where it is - why
In ArcCatalog, if you've just created a new layer in ArcMap, it may not appear until you refresh the list. To refresh the list, use F5.
Labels
You can label features (ugh, an arc word...) with their attributes (ugh, another arc word). There is a toolbar for it.
You might need to be in an open Edit Session for this to work.
View -> Toolbars -> Labeling
The first icon is the Label Manager.
Linear referencing: point location along the line as an alternative to expressing the location using an xy coordinate. Useful, for example, for measuring distance along a stream.
An Overview of Linear Referencing
Here are steps outlining a way to put hatch marks (with distance labels) on a polyline (e.g. following a stream).
1. When you create the polyline shapefile in arc catalog, you need to
.e00 files are from an older version of arc. a simpler time. but now it is complicated to open them.
I ended up importing some .e00 files that were in a .tar.Z file (1996 USGS Open report) in a very roundabout manner, and later found some other more straightforward procedures (but can't figure out how to get those to work with my version of Arc). I'll just post them all here.
1. Official
Simple:
Toolbox -> Spatial Analyst Tools -> Surface -> Contour
Specify input raster, output name, contour interval.
Creating contours in spatial analyst
This is how I got an xyz table of a bunch of points. (There is probably a better way out there.)
1. Using arc catalog, create a shapefile of points. Then add columns to the attribute table, x, y
2. In arcmap, start an edit session and click away on the points.
3. End and save edit session, I think.
4. Right click on shapefile in Table of Contents column and open Attribute Table. All of the
While hunting around for some guidance in producing a slope map (a matter of a few mouse clicks), I came across this page [aspect-slope map], which is useful because it gave an example of how to implement the following things:
Styles (predefined colors, symbols, map elements, etc.)
Slope map (with link to how it works)
Aspect map
Reclassify: redefine the default number and width of display bins
I wanted to find the mean, min, max, stddev elevation of a bunch of traced terraces, but this can be done with any input files of a zone dataset (i.e. shapefile of polygons) and a value raster (i.e. raster of elevation values).
1. Make the zone dataset, in my case, make a shapefile of polygons [make polygon layer]
2. Add field(s) to the Attribute Table to define the zones. I have a separate ID
