(1)Partial explanation of errors. Quick Plan was used with a current Almanac to determine the more opportune hours to collect data. Increasing foliage during the data collection time period made collecting coordinates in certain areas less than ideal and as a result, introduced positional errors. Some of the data was edited during post collection processing. Visually radical position points as well as those incongruent with what was remembered as walked were mostly removed. Post processing with the COR files improved the temporal positional quality for some points, hopefully to be further edited for accuracy when time permits. When radical points exist in the collected raw files, they may still be converted. Some points are removed during the post processing because the point's attributes/characteristics fall outside the software/processing parameters. Even if the points meet the criteria, but are in the wrong location, they are still wrong regardless of whether or not they were processed and the fact that they were processed does not indicate a correct location.

A paper with more details and explanation for one segment of this project is available in Word or PDF format. The Word document has active links referencing other pages that visually show what is being referred to. The links ask for a user name and password sometimes, canceling seems to let them open. None of them are running scripts. The links require backing up and reopening the main document after opening, will find out how to open them in a new page.

The shp, dbf, shx, and prj files need to be downloaded individually into one folder and then the shp file loaded into ArcMAP.

The ArcMap mxd file is available and needs to have everything in the same folder. The files making up the layer used as a background are Digital OrthoPhoto Quads or DOQ files in SID format and will require bandwidth and space if downloaded or sent. The project is about 104 MB so far.

The KML files overlay on Google earth nicely. A JPG can be saved at any point during viewing.

If Google Earth is already installed and you have opened KML files before, click on the file and when the pop up asks to save or open, click on open and Google Earth may open automatically and zoom to the selected trail being displayed.

To use the KML files with Google Earth:

1) Open the desired KML file above and when prompted, save to an area on the computer you will remember. Example: My Documents or Desktop

2) Open Google Earth.

3) At the top go to File and click, then to Open and click, then browse to the area where the KML file is saved, click ok or open.

Should open and zoom to the displayed file. The process can be repeated numerous times until all the files are displayed at once. On exit, save the temporary places and they will be available next time Google Earth is opened. The thumbnail below opens a print screen of the trails displayed using Google Earth.

Can Google Maps read the KML files I've made for Google Earth?
