creating maps for location, home range #35

Closed xhdong-umd closed 6 years ago

xhdong-umd commented 6 years ago

I'm working on maps for animal locations, home range/occurrence polygons.

@chfleming , the SpatialPolygonsDataFrame.UD returned the polygon coordinates as relative x,y values (Two-Point Equidistant projection?), not the absolute coordinates. There are reference coordinates in standard parallels of proj4string, so supposedly this should work, indeed the shapefiles(which have same structure) can be plotted in right location.

However I'm having trouble plotting SpatialPolygonsDataFrame in right location.

Should I reproject the data?

Yes, I used ggmap to produce the figures, but you're right leaflet is much more useful when exploring the data.

My thinking was that once users had found a static map they found interesting they could export this in publication quality. Of course, if the logistics behind this option is too complicated, then we can drop that feature. Many users will be able to do this by exporting the shape files and doing similar in GIS.

Do you guys find these features useful?

measure, let user click two point and measure its distance. I think this is good.

add a grid. I'm not sure about this since there is no label on lines. The grid can be switched off with layer selector. Should we use the term Graticule or just grid lines?

NoonanM commented 6 years ago

I think measure would be useful, not so sure about grid.

xhdong-umd commented 6 years ago

I found another option to add grid with labels.

xhdong-umd commented 6 years ago

The measure can measure lines or polygons

Point map now can take the bounds of heatmap. Though it might have a lower zoom level, which seemed to be a limit of current existing Shiny support on leaflet.

xhdong-umd commented 6 years ago

I added map to report and save features:

when map was created, a copy was saved in report folder and will be included when report zip was downloaded.
If user changed the view of map (pan and zoom), clicking download map will save the current map with current bounds. This customized version will also be included in work report.
Unfortunately, there don't seemed to be a method in R to save the user created measurement in the html. There are some javascript methods to do this. If this is really needed, I can try to look at the javascript way, though I'm not quite familiar with it.

There seemed to be some problems with applying heatmap bounds to point map in hosted app. However I can't find any error message or log entries for this. I'll look at this tomorrow.

xhdong-umd commented 6 years ago

The problem with hosted app seemed to be fixed.
I added help document for map page.

I think most of map features are completed except

We discussed about the method that switch big data set heatmap to points layer if zoomed in enough level. Now with the point map sync with heatmap bounds I think this is not needed, as adding points data to heatmap will make it bigger and slower to create.
I haven't really look into animation feature yet. I'll add this to my list and maybe revisit it later.

@chfleming The dAICc column is calculated from summary on list of models, but there is no summary function for list of home ranges, so this column is not included in the home range model summary table now. Should we take the dAICc value from previous page and add to the home range summary table?

Is it under consideration to be able to mix both the home range and occurrence distribution maps as a single map. I'm aware that they are two difference distribution, but it could be informative to visualize.

xhdong-umd commented 6 years ago

The occurrence distribution plot is rather complex. Currently it's a ctmm function implemented with base plot. To convert it into a leaflet map will be quite difficult, basically need to implement all details again in a different platform. I'm not sure if that's doable or worth the effort.

vestlink commented 6 years ago

I agree.
