Title: Instructions for Uploading Points and Photos for Linking


1
Instructions for Uploading Points and Photos for
Linking
  • Uploading GPS points requires the following
  • At each site or transect note stop, mark a GPS
    waypoint, label it using the 3 digit transect
    number and 2 digit stop number or your chosen
    numbering scheme (Example 00601).
  • Using MN-DNR Garmin application, save the points
    to a .txt file (Example 06FG.txt) to appropriate
    survey area folder on your system (Example
    C\pedon\gps_upload). See Using MN-DNR Garmin
    for expanded instructions.
  • You do not need to be concerned with uploading
    duplicate points. The database will only upload
    points from the .txt file that do not already
    exist as records in the database.

Using MN-DNR Garmin
  • Use the MN DNR Garmin stand alone application to
    upload waypoints and save them as a .txt file.
  • If you dont have the MN DNR Garmin application,
    you can obtain the most recent version from
    http//www.dnr.state.mn.us/mis/gis/tools/arcview/e
    xtensions/DNRGarmin/DNRGarmin.html
  • Plug GPS in to the serial port of computer.
  • Turn GPS on.
  • Open MN DNR Garmin application.
  • Navigate to Waypoint gtgt Waypoint Properties
  • On the projection tab set projection using the
    drop down list (Example NAD_1983_UTM_Zone_12N)
  • On the waypoint tab, REMOVE the check marks from
    all BUT the following fields type, ident, lat,
    long, y_proj, x_proj, comment, altitude.
  • Navigate to Waypoint gtgt Download
  • Records from GPS should appear in the dialog
    window.
  • Once records are as you want them to appear (you
    can remove unwanted records, rename records,
    etc.) navigate to File gtgt Save To gtgt File and
    save as .txt file

Linking Photos
  • Start the Pedon PC
  • Select Forms gtgt Drill Down Analysis form on the
    forms menu
  • Once the Analysis form is open click on the
    launch GPS form button to open the GPS import
    form.
  • Browse to the location of the text file your
    points that you just created using DNR Garmin.
    Notice that the records from the text file are
    loaded and show up in the table within the form.
    Similar to DNR Garmin, you can delete or change
    any records that you want to before they are
    imported to the database. Select the proper
    settings for the remaining fields on the form.
  • If your initials do not show up in the dropdown
    list for describer you will need to add them to
    the custom choice lists by going to Setup on the
    main menu gtgt Customize Choice Lists gtgt Edit
    Choice Lists. Once the form opens click on the
    plus next to the soil_survey_personnel domain and
    either overwrite an existing record of initials
    and name or create a new record at the bottom of
    the table.
  • The import process will take the 4 to 6 digit
    number logged in your GPS unit and will build the
    user site id based on your entries to the fields
    on the form. For example, I selected my user
    site id format as Date, Survey Area, Garmin Ident
    Field. The date is 07, the survey area is
    MT645 and the point number in my GPS is 1001,
    so the user site id in the database will be
    07MT6451001.

Instructions for Uploading Points and Photos for
Linking
  • Date-matching Photos to GPS points in the Pedon
    PC requires the following
  • That you synchronize the date/time on your camera
    with the date/time that your Garmin GPSmap 76
    receives from the satellites, the format of the
    camera date is not important for this to work).
  • Remember Each time you change the batteries in
    your camera you will need to check and
    re-synchronize the time.
  • Try to take any photo documentation within
    minutes of marking a GPS waypoint. Photos will be
    matched to the nearest site or transect stop by
    date/time based on a time window that you specify
    (5 minutes, 15 minutes, etc.)
  • Copy photos directly from camera to common
    location on S drive. You are responsible for
    maintaining your original full resolution photos
    locally.
  • Important Do not use a 3rd party application
    (such as Cammedia, etc) to move, rename, rotate,
    or otherwise modify the photos until they are
    linked to stops.
  • In order to avoid cross-linking of photos when
    the pedon.mdb file is in a shared location, it is
    recommended that you set up a file structure that
    will not allow this to happen (See File Structure
    slide).
  • Recommended Picture Quality should be set to
    Best and Picture Resolution to High on your
    camera.

5
File Structure for Storing Photos
  • Create a folder and label it with the year and
    then create a named folder each project member
    within it at a common location on the shared
    drive. (see below)
  • Plug in your camera and copy your photos directly
    from your camera into the folder with your name
    on it.

6
Linking Photos
  • Start the Pedon PC
  • Select Forms gtgt Analyze Point Data on the forms
    menu
  • Once the Analysis form is open create and save a
    filter that pulls only records you have added to
    the database for that year by uploading your GPS
    points.
  • To do this go to the shortcut drop down in the
    upper left of the form and select the field
    Describer, then go down into the PickList and
    click on your initials. Notice the filter moves
    into the filter box
  • (pedon.descname 'JMS')
  • If you want to further reduce your selected set
    to only those points with your initials and user
    site ids that have the year 07 in them then add
    the following (pedon.descname 'JMS') AND
    (site.usiteid LIKE '07')
  • You can copy and paste this filter into the box
    and then change the initials.
  • Now save this filter (Example JMS_2007 points)
    and use it to filter to your points each time you
    wish to link photos to your points. Each project
    member should create a similar filter and save
    it.

Linking Photos
  • Now click on the Open Photo Manager button
  • Go to the drop down in the upper left hand corner
    of the form and select Selected Sites Drill
    Down Analysis Form to load the filtered set from
    the analysis form.
  • Go over to the dropdown on the upper right hand
    corner of the form and check that only your sites
    were loaded and appear in the list of site
    observations.
  • Browse to the folder with your name on it where
    you have stored your photos.
  • Now go to the drop down in the upper left hand
    corner of the form and select Directory (Link by
    Nearest Date-Match). This will start the date
    matching of photos in the specified directory
    location to the site records in your filtered set
    from the analysis form.
  • A prompt will confirm what you are about to do,
    click yes if you are ready to create the photo
    link records.

Linking Photos
  • A message will appear that tells you the date
    match tolerance (time window) that you are using
    to link the photos, how many sites had new links
    created for them, how many sites already had
    links, and the number of photos that remain
    unlinked. Click OK to all of these, then click
    Yes to show all photo categories.
  • Photos will be loaded on the left side of the
    form. Click on the Site Observation dropdown
    list and select a user site id to view the photos
    that are linked to that site on the right hand
    side of the form.
  • Click on an image on the left or right sides of
    the form and it will load into the center frame.
    You can change the photo category of a photo to
    further describe what the subject of the photo is
    and you can enter a short caption (20 character
    limit).
