salem.GoogleVisibleMap
- class salem.GoogleVisibleMap(x, y, crs=<Other Coordinate Operation Transformer: longlat> Description: PROJ-based coordinate operation Area of Use: - undefined, size_x=640, size_y=640, scale=1, maptype='satellite', use_cache=True, **kwargs)[source]
Google static map automatically sized and zoomed to a selected region.
It’s usually more practical to use than GoogleCenterMap.
- __init__(x, y, crs=<Other Coordinate Operation Transformer: longlat> Description: PROJ-based coordinate operation Area of Use: - undefined, size_x=640, size_y=640, scale=1, maptype='satellite', use_cache=True, **kwargs)[source]
Initialize
- Parameters:
- xarray
x coordinates of the points to include on the map
- yarray
y coordinates of the points to include on the map
- crsproj or Grid
coordinate reference system of x, y
- size_xint
image size
- size_yint
image size
- scaleint
image scaling factor. 1, 2. 2 is higher resolution but takes longer to download
- maptypestr, default: ‘satellite’
‘roadmap’, ‘satellite’, ‘hybrid’, ‘terrain’
- use_cachebool, default: True
store the downloaded image in the cache to avoid future downloads
- kwargs**
any keyword accepted by motionless.CenterMap (e.g. key for the API)
Notes
To obtain the exact domain specified in x and y you may have to play with the size_x and size_y kwargs.
Methods
__init__(x, y[, crs, size_x, size_y, scale, ...])Initialize
get_vardata([var_id])Return and subset the image.
set_period([t0, t1])Set a period of interest for the dataset.
set_roi([shape, geometry, crs, grid, ...])Set a region of interest for the dataset.
set_subset([corners, crs, toroi, margin])Set a subset for the dataset.
Attributes
roiMask of the ROI (same size as subset).
