And where exactly do you change the annotation layer's transparency?

1 bonus question for you guys. I have a corridor or route that I want to show preferential treatment too. Is there anyway I can reclassify a raster and give it a negative value to subtract away from the cost of other rasters that may be on top of it?

‎03-05-2013

That makes perfect sense. Thanks!

Have you tried the Data Management Tools.tbx\Raster\Raster Dataset\Mosaic command? This doesn't add them, it has several options such as use the value of the last raster listed. This will leave your values alone. Following up question. Now that my rasters are merged. How does my Cost Weight know that 4 is bad and 1 is good and not vice-versa?

Jared - One way to learn more about the least cost path workflow is to register for the Distance Analysis using ArcGIS 10 web course. It goes into straight line distance and least cost path analysis workflows that may assist you. I teach the now retired Spatial Analyst class for Esri - feel free to email at rleclair@esri.com if you have specific questions. Regards, Robert LeClair Esri-Denver Thanks for the reply Robert. Do they offer that course for Arcmap 9.3?

I have now converted my polygons into rasters and then reclassified them. My four layers are now reclassified with the values of "4" (4 will be my thou shall not pass number) I then reclassified my reclassified DEM with the values of 1,2,3 and 4. (4 being the high elevation to avoid) --- I then read that you need to merge these together by using the raster calculator and adding these values together. When I do, it generates a calculation raster with a High: 2147483647 and a low of -2147483648! What happened to my neat and tight 1,2,3,4 values??

Ok seems like I'm not getting much help so I'm going to post my trials and errors here. Looks like my first step is to take my very large(geographically) DEM and clip it to just the area I want. So I created a polygon over the parts of the DEM that I want to clip. Then I went to the Toolbox - Data Management Tools - Raster - Raster Processing - Clip. I then found out I need to reclassify my newly clipped DEM. (why I'm not sure) I turned Spatial Analyst extension on. Then selected my clipped DEM in the drop down box. Then clicked Spatial Analyst - Reclassify. I choose to have 8 unique values based on the range of elevation. Those 8 values I assume I will be given weighted values later on. ie. 1-4 no cost, 4-6 medium cost, 7 high and 8 avoid. ---- That now leaves me with my shapefiles (Which I want to weigh differently) that I guess I now need to reclassify. I assume I will have to turn these polygons and points into rasters as well...

I have never used Least Cost Path before and the online help is WAY over my head. Can someone please break it down for me how to find the Least Cost Path between 2 points? -- The data I have to weigh this path is as follows: One NED from USGS with elevation in meters. 2 points (My start and end points) 4 High Consquence areas polygons (ecological sensitive, drinking water, other populated, and highly populated) thanks, Jared

Are their any versions on the internet where the SSURGO shapefiles with the musym field are not abbreviated? I know I can join them via access database. But I need to do ever county in Texas and this is going to be a pain in the butt.

I simply want to edit my attribute table and type in a new xy coordinate and have it display on my map.

‎07-16-2012

I have a shapefile with X and Y data plotted on my map. I want to be able to add additonal points to the attirubte table and have it update on my map immediately. Is that possible without running the "Add XY Data" option?

Thank you!

I'm currently trying to find the distance of mulitple polylines(rivers) in multiple polygons(counties) Tried this and failed. *ArcToolbox - Analysis Tools - Extract - Clip. That process returned a unclipped shapefile. Tried this and failed. *HawthsTools Sum Line Lengths in Polygons. I get the following error: LinesInPolys:K -2147216814 The geometry property of the spatial filter is invalid. Note. I have Arcmap v. 9.3 My coordinate system is = NAD_1983 as is my polyline and polygon layer. I have also run the check geometry tool and everything checks out. Anyone have an idea of what I could be missing? Or know of any work arounds?
