Add data

Before you starts to add any data, please ensure that you have added a least one field and one crop.
Then to add data go to the second tab of the main GeoDataFarm window (Import data).
Import data
Here are 10 different sub tabs with different types of data (Planting, Fertilizing, Spraying etc.) that you can add to your farm. I will now show how to add some planting data, adding other data is similar.
If you have GPS connected to your tractor/ the machine can log data with GPS coordinates, you can import these to the program, otherwise you can add some data by filling in them in the right part of window.
But if you have GPS logged data you can load them in to the program, choose file type (at the moment is it only possible to add text data (.txt/.csv files). When you press Open the file and save it you get following dialog.
Import text data

  1. Press "Add input file" and select your text file that you want to upload to GeoDataFarm, when this is added the upper field will be filled in like the illustration above.
  2. Select which field the data covers, it is important that you choose the correct field, data points outside the field will not be loaded.
  3. Select crop.
  4. Select coordinate system(EPSG), If you have a column with latitude and longitude it is probably WGS84, EPSG: 4326.
  5. Separator, the program tries to identify what separator that is used in the text file, if you can't see the columns after you added the file try changing the separator.
  6. The first column is the heading row of your file, the second is the first data row the third is a guess of what kind of data the column consists of. There are three types of data, integer, decimal value character, make a quick check so the program has guessed the correct type of data.
  7. Select rows in the left table that would be interesting to analyse and "move" them to the right table.
  8. The columns that you have here will later be loaded as separate layers, this list can be alter later. When you have columns in the left side here you can press continue.
  9. When you press continue, the lower part of the dialog is filled in, Make sure that the program has guessed the correct N(orth) and E(ast) columns.
  10. Select the correct column that corresponds to the attribute at the left side. (In the case of planting, Variety), if no columns correspond to the attribute you can either give all data points the same value or exclude that column.
  11. Date, either you have a column in your file with a correct date or you fill it manual (then all data points gets the same date). If you have a column with the date you also need to specify which format the data is in.
  12. When you press Save data the program will start to import the data, this can take a few minutes if your data file is large.
When the data is loaded, multiple layers (one for each row in the left table) will be added to the QGIS canvas. On the left side of the screen there is a list of the layer names, the layer on top will be the layer on top of the others in the canvas. if you press the down arrow Arrow next to the layer name you'll get a legend of what the colors indicates. If you "untick" the checkbox the layer disappears.
