Devise grid cell labelling scheme #64

Closed dbl3raf closed 6 years ago

dbl3raf commented 6 years ago

what are the dimensions of the matrix of atlas squares? If there's any way you could send me the shapefile of the current 2km grid that would be brilliant

jeffreyhanson commented 6 years ago

Sure, I've uploaded a zip file with the grid here (grid.zip).

So the decision is that any code will do for the grid cells, and they will in the end have unique text-based names, like Carindale South, Holland Park East etc. I suggest just using a uniquely indexed integer field to be a "primary key" and then add another text field, into which I can start putting names as we make them. You could always initialise the text field with the numbers used for the primary key, until I get around to replacing each square name. Does this work?

jeffreyhanson commented 6 years ago

Yeah, that works great. I can't remember - did we want to integrate the grid id's into the atlas itself? Or is this purely for the sampling sheets? I suppose we could have the interactive maps display the grid id if the grid cell is double clicked on?

dbl3raf commented 6 years ago

Initially this was for the survey sheets, but yes it would be brilliant if the grid square name could display if the cell is doubled clicked on - that would help the user identify a square. Maybe down the track we might be able to add a URL so they can download the survey sheet for that particular grid cell.

I've updated the atlas so that the data/grid/grid.shp file now contains the 2 x 2 km grid cells. It has an integer "id" field and a text "name" field in the attribute table. On the online version of the atlas, if you go to one of the species accounts (e.g. http://brisbanebirds.com/magpie-goose-anseranas-semipalmata.html#magpie-goose-anseranas-semipalmata), scroll down to the interactive map, then click on the "Grid" checkbox in the map, and then click on one of the black grid cells, you should see a popup. This popup currently displays the text in the "name" field of the grid shapefile - so once you've got "proper" names for all the grid cells then I can remake the interactive maps so they display the "proper" names.
