Editing

* Do it ASAP, before collecting more data, if at all possible.

* Scrutinize before you edit, check your memory and your field notes before you edit.

* Keep a copy of the original unedited file! Pathfinder does not do this for you automatically.

* Check features, attributes and spatial pattern.


Editing1

Editing

Point Features: Location

Is the point misplaced relative to other features or an expected pattern?

Check the corrected positions that the point is

based on. Check field notes for constellation

jumps, PDOP spikes.

Point Features: Theme

Is the feature correct?

Are the attributes correct?


Editing2

Editing

Line and Area Features: Location

Are features in the right location relative to each

other?

Are straight lines straight?

Are curves and corners fully spatially defined with

enough vertices?

Are there too many vertices?

Do any arcs cross?

System Tab: DOS files

Attribute Tab: Attribute value (or one of the code values, see the .ddf)

may also include attributes such as PDOP, date, etc. see list

maximum PDOP: 4 (5)

include:diff corr positions

Coordinate System Tab: Select “Export Coordinate System”, then

specify: UTM; Zone 19 north; NAD 1983 (CONUS)
