Export a survey

Exports turn a saved survey into a standard file you can open elsewhere: in your design software, a GIS, Google Earth, or the Job Viewer. Where you export from depends on the kind of survey.

Every export is saved in Documents/DitchAssist/exports/ on the tablet. Coordinates are latitude/longitude (WGS84) and elevations are in metres.

Before you start

Time: about a minute per export.

• The survey is saved. Exports work from saved surveys only.
• The app has All files access, so the file lands where you can find it (Check All files access).
• To send the file by email or Drive: the tablet is on Wi-Fi with internet (Wi-Fi on the tablet).

Export a route survey (XYZ or KML)

Tap Survey

On the Home screen, tap Survey: the second button in the column down the right side. It works once a workflow is open (a card on Home shows ACTIVE). The Survey screen opens with the map.

Tap Load

At the bottom of the column of buttons down the right side: a dark button with a folder icon. A window called Load opens on the Surveys tab.

1

Tap the share icon on the survey's row

Find the survey by its name. Surveys are grouped by day, newest first. On its row, tap the share icon: a box with an arrow pointing up, between Load and the trash can. A small menu opens.

Tap Export XYZ or Export KML

• Export XYZ: a text file, one point per line, tab-separated: latitude, longitude, elevation in metres.
• Export KML: opens in Google Earth. A green line for the route plus a pin per point with its elevation and distance in feet.

The file is saved

The menu closes and the Load window stays open. A message starting Exported: shows for a few seconds along the bottom, behind the dimmed window, so you may hardly see it. The file is saved anyway.

Close the window with the X at its top right.

There's no Share button for these exports. Copy the file from Documents/DitchAssist/exports with a USB cable, or share it from the tablet's My Files app. Both are shown in Move files to and from the tablet. The file is named after the survey, with a long number on the end, so a new export never replaces an old one.

Survey elevations already have the blade height taken off, so they are ground elevations. They are in the frame of the base station used that day; calibrate to a benchmark when you bring a design back from another program.

An XYZ export can go back into the app on another tablet, with Import survey file (XYZ / XYZP) at the top of the Load window in Ditching, Excavation or Tiling.

Export a whole-field survey

Field Survey is the whole-field survey you drive for Levee, contour work or Land Forming. These steps start in Levee; the contour workflows and Land Forming open the same Field Survey screen from their own survey button.

1. Tap the Levee card on Home

   It's in the bottom row of the nine cards, in the middle. Connect, or tap Simulate, if the app asks (Connect to your kit). The Contour Guidance choices appear.

2. Tap Survey New Field

   The first choice under Contour Guidance. When saved field surveys exist, a window called Resume or export existing survey opens.

   1

3. Tap the survey

   Each saved survey is listed with its points, sessions and date. Tap the one to export. A window called Survey actions opens.

   1

4. Tap a format

   The formats are listed under Export formats, below Resume survey.

5. Tap Share, or Done

   A window reads Exported to and the file name, with the full path under it. Tap Share to send the file straight to email, Drive or Quick Share (email and Drive need internet). Tap Done to leave it in exports.

Pick the format here:

Ask the person who will use the file which one they want. CSV and Shapefile suit most GIS and drainage design programs.

Export from Levee

Levee can export a saved field survey from its own list, in five formats. Shapefile and LandXML are only in Field Survey (above).

1. Tap Use Existing Data

   The second choice under Contour Guidance, when you open Levee from Home. The Levee screen shows its Contour Guidance panel with a row of coloured buttons.

   1

2. Tap Saved Survey

   The orange button under Or use existing data, on the left. A window called Load Saved Survey opens.

   1

3. Tap the share icon on the survey's row

   The box with an up arrow at the right end of the row, left of the trash can. A window called Export format opens: WGS84 (EPSG:4326). Elevation in meters. Saved under /Documents/DitchAssist/exports/

   1

4. Tap a format

   CSV, TSV, XYZ (space or semicolon) or KML. The window closes.

5. Tap Share in the message, if you want to send it

   A message along the bottom of the screen reads Exported to and the file name, with Share at its right end. To close the message without sharing, swipe it down.
