II. Browse toolbar


To view map and move around map

The first 3 menus are for setting zoom, pan and extent of map

These including Zoom to Layer, Center on GPS & Bookmarks

III. Command toolbar


Lock/Unlock screen to prevent accidental screen taps 1d-lock

The Toggle Pen button turns off digitizing - only GPS can be used for editing 1e-nopencil

IV. Basic data collection techniques

For EVERY feature -

1. Choose layer to edit

2. From edit tool bar and choose polyline or polygon (not needed for


3. Choose GPS tool (point, vertex, stream)

4. Complete the geometry with green arrow (polyline and polygon)

5. Enter attributes

6. Click ok to save features

A. Point

1. Choose layer to be edited via the Start/Stop Editing Tool 1f-spencil

Note: Only Point, Polyline and Polygon are for GPS Capture

All other items are for digitizing ONLY

2. To start collecting GPS positions, tap on GPS-POINT 1g-gps_pt

3. Enter attributes as needed

4. At the top, left corner of window is the % of required positions already collected for averaging. This value was set in the GPS Preferences Capture tab

5. Geography Tab to view coordinate position

6. Optional: Tap the GPS button 1h-regps to start over and re-collect positions

7. Tap OK to save feature

Note: For features of any Geometry type, on the Edit toolbar / Offset menu, Repeat Attributes 1i-repeat will copy attribute values entered for any previous collected with any matching attribute field.

B. Line or Polygon by Streaming

  1. Choose layer to be edited via The Start/Stop Editing Tool 1f-spencil
  2. From the Point drop-down menu, tap on POLYLINE (not line) 1j-polyline or POLYGON 1k-polygon
  1. Position antennae over desired location
  2. Tap on GPS-Stream 1l-gps_stream to start collecting in stream mode
  3. Move to collect continuous vertices for feature at the interval as specified in the GPS Preferences Capture tab
  4. Tap on GPS-Stream to pause collecting, re-tap GPS-Stream to continue collection
  5. At end of the feature, tap PROCEED 1m-green_arrow
  6. Enter attributes as needed
  7. Tap OK to save feature

When streaming, be sure to collect a position at defining turns and corners.  For more the most accuracy, collect these as an averaged vertex.

C. Line or Polygon by Vertices

Choose layer to be edited via The Start/Stop Editing Tool 1f-spencil

  1. From the Point drop-down menu, tap on POLYLINE (not line) 1j-polylineor POLYGON 1k-polygon
  2. Position antennae over desired location
  3. Tap on GPS-Vertex 1n-gps_vertexto start collecting positions to averaged for vertex
  4. Wait until all positions are collected
  5. Move to next vertex
  6. Repeat steps 3-6 as needed
  7. (Optional) To delete the most recently collected vertex, tap the Undo

button on command toolbar.

  1. At end of the feature, tap PROCEED 1m-green_arrow
  2. Enter attributes as needed
  3. Tap OK to save feature

V. To review collected features and their attributes

1. Query tool to review attributes of collected features  1o-binoc

2. Query tab to enter search criteria; no search criteria lists all features

3. Results tab lists resulting feature(s)

4. Tap any feature, to select it. It will also be highlighted in blue on the map

5. When finished Clear selected features on the map from Query menu 1p-clr_features

Query Results window


VI. To delete a feature

1. Select a feature from the map with the Select tool 1r-blk_arrow

2. To identify the layer in which the feature resides, tap the Feature Properties tool 1s-att_table

3. The layer name is listed at the top of the window

4. Choose that layer to be edited via The Start/Stop Editing Tool 1f-spencil

5. Tap the Feature Properties menu, choose Delete Feature 1t-x

VII. To complete the field session

Features are saved once OK is tapped

It is not necessary to save changes to the .ArcPad map (apm)

Disconnect GPS

From the Main toolbar , Exit ArcPad  1u-exit

Note: X’ing out of ArcPad only minimizes, but does not exit the program
