Load Layer: Important Bird Areas (IBAs) - Australia #37

Closed Tasilee closed 6 years ago

Tasilee commented 9 years ago

The Important Bird (and Biodiversity) Areas (see http://www.birdlife.org.au/projects/important-bird-areas/iba-maps) are internationally recognised and IUCN-supported area of significane for bird species. They are in addition to CAPAD areas.

Criteria for IBAs (metadata): http://www.birdlife.org/datazone/info/ibacritglob

International data: http://www.birdlife.org/datazone/geomap.php?r=i&bbox=-150%20-50%20150%2080 but can't see how to get GIS data.

No counterparts to deprecate.

Could only find Australian IBAs. Needs metadata.

name: iba_australia id: 2087

Tasilee commented 9 years ago

At this stage, let's just load the Australian IBAs, the shapefile and kml files are at http://www.birdlife.org.au/projects/important-bird-areas/iba-maps. I'll do the metadata now.

On prod.

Tasilee commented 9 years ago

Were there classes in the data to class areas as "seabird island species", "resident waterbirds", "migratory shorebirds", "mallee birds", "threatened woodland birds", "rainforest birds" and "other"?

Just to clarify, did you want a single category based field or a field for each category?

The field list for the source behind 2087 currently is:

The international data is available under a non-commercial and not to be distributed license, so not sure what we could use it, as anything we would use it for would be distribution:

We need to draw the line somewhere rational on what international layers we include. I'd skip this one as there is a case for analysis of Oz data but not external.

On your other question about the categories though, there doesn't seem to be any metadata or data dictionary attached to the australian iba shapefile, so not completely sure how to interpret most of the fields, but the unique values for the latter fields are the following if that helps:

Field Name  Unique Values
REGENT_HE   0, 1
CARNABY_BC  0, 1
CAR_BAU_BC  0, 1
AUST_BITT   0, 1
FAIRY_TERN  0, 1
SWIFT_PARR  0, 1, 2
WATERBIRDS  0, 1, 2, 3, 4
THREAT_STA  0, 1, 2, 3, 4
IBA_CRITER  1, 2, 3, 4

The IBA_CRITER column may refer to A1/A2/A3/A4 from http://www.birdlife.org/datazone/info/ibacritglob

The THREAT_STA column may refer to the Red List categories, but no idea how they would map http://www.birdlife.org/datazone/info/spcredcat

The others except for WATERBIRDS all seem to be species specific so they may benefit from a special species distribution for those.

Without a lookup, it is hard to say. Suggest you marry an example as in http://www.birdlife.org/datazone/sitefactsheet.php?id=24809 and hopefully the values will be determined?
