# Purpose of this script is to fetch parts of a map and reconstruct it
# It's suited to fecth maps available at www.geo.ulg.ac.be/edusat/en/ikonos

#
# History:
# * Version 0.3:
# XY Coord computation made easier, no more need for bc
# Support for additional maps: all Liege Ikonos are now supported
# * Version 0.2:
# Fix parametrization of total nr of images
# Fetch more robust: retry if download failed

# Here are the parameters to adapt:

## Give just a prefix for the saved images

## Size of the whole image to recover, quite hard to guess I agree...

###############################################################
# This should not be changed:
# Zoom is currently between 0 (max) and 17 (whole world in one tile)

# Scale between YYY and Xxxxxx data: (experimental)
SCALE_YYY=1.046613
###############################################################
# PARAMETERS
# PREFIX:
# Simply the prefix to append to temporary and final files
# UPPERLEFT:
# This script accepts UPPERLEFT input in qrst string format (as kh.xxxxxx.com)
# or in H:V:Z format (as mt.xxxxxx.com)
# To find qrst or H:V:Z coordinates, go to maps.xxxxxx.com, satellite view,
# navigates to the desired upper-left corner, page info->media->check images
# NR_H_TILES and NR_V_TILES:
# Indicate the nr of horizontal and vertical cells to retrieve
# PROJ=[2-3]
# Projection can be Mercator projection => PROJ=3
# cf http://en.wikipedia.org/wiki/Mercator_projection
# or Plate carree (equidistant cylindral projection) => PROJ=2
# cf http://en.wikipedia.org/wiki/Plate_carr%C3%A9e_projection
# When making hybrid maps, be sure to use PROJ=3!
# Default:
# PROJ=3
# SAT_SOURCE=[XXXXXX|YYY]:
# Select source of satellite views
# Remark: YYY satellite views are already with metadata
# and the script takes directly UPPERLEFT as YYY coordinates
# so providing SAT_SOURCE=YYY + some HYBRID_* will go wrong!
# Anyway who wants their poor outdated satellite views??
# Default:
# SAT_SOURCE=XXXXXX
# HYBRID_XXXXXX=[false|true]
# HYBRID_YYY=[false|true]
# Combines satellite view with vectorized data
# Can be data from Xxxxxx or from YYY
# YYY metadata are not transparent and not aligned with Xxxxxx data
# but who cares? the script make them transparent and aligned :-)
# This is particularly interesting for non-US locations where
# Xxxxxx metadata is very poor.
# Default:
# HYBRID_XXXXXX=false
# HYBRID_YYY=false
# HYBRID_YYY_CLEAN=0x[0-F]
# Bits indicate which elements to remove:
# 1: Remove land
# 2: Remove sea
# 3: Remove sea coast
# 4: Remove inner frontiers
# Best combinations are probably 0x3, 0x7 and 0xF
# Default:
# HYBRID_YYY_CLEAN=0xF
# HYBRID_YYY_WHEN=[BEFORE_HYBRID_XXXXXX|AFTER_HYBRID_XXXXXX]
# If both metadata, in which order to apply them?
# Default:
# HYBRID_YYY_WHEN=AFTER_HYBRID_XXXXXX
# For ease of use, the script can be called for direct conversions as such:
# gmaps <qrst string>
# gmaps <horizontal int> <vertical int> <zoom>
