Sample of Raw Range Data
This is the raw LDU frequency data we started with for Leptochidium albociliatum. The color legend is:
||areas where it is known to be frequent
||areas where it is known to be at least infrequent
||we have data for these LDUs but no records of it occurring there
||we have no reliable data for these LDUs
||shows how the raw data will be smoothed off for the final map going in the book
We are scrutinizing literally over a thousand such maps as you read this. In the final product we will distinguish between regions where it is known to occur and regions where we it is presumed to occur.
Here is the completed map. And here is a full-size TIFF (1Mb).
