My map opens with QGIS saying "This layer seems to have no projection specification" and generates the following CRS: +proj=aea +lat_1=31.5 +lat_2=24 +lat_0=24 +lon_0=-84 +x_0=400000 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

Looks like some form of Lat/Lon coordinates. How can I transform to WGS?

    What do you mean by map. Do you mean a Raster file or a shapefile. If you want to change the projection of your files, you can simply right click on your file and export it into a different CRS (4326). If you want to change the projection of your project, look at the bottom right of your page where it says EPSG:xxxx. click on that and change it to the projection you would like to visualize your project. – B-C B.

  • Welcome to GIS.SE! What are the extents of the layer? Where did the data come from? Ask them/check the website to see if there's any information. – mkennedy Feb 21 at 22:50

QGIS try to read the CRS from the .qpj file, if exists. In your case, it doesn't.

When not finding a .qpj file, try to read the projection parameters from a .prj file. And write a custom CRS with that parameters.

In your case, seems to me that you file has the EPSG:3086 CRS, but was saved by another software (because a .qpj file was not written).

You can export the layer to reproject it to WGS84.
