Lunar example for spec appendix #15

Closed thareUSGS closed 5 years ago

thareUSGS commented 6 years ago

Perhaps placed in the informative " D.8.2 Less Common Examples " section (or an appendix).

Goals for this addition is to display a very simple extraterrestrial example (e.g. a spherical Moon). But this example, often requiring "User-Defined", shows how more custom Earth-base examples could also be defined. I think it highlights the flexibility for a GeoTiff label.

Note this example (using listgeo), is showing the header values as mapped strings instead of the original short Integer. e.g. GTModelTypeGeoKey = ModelTypeProjected (which is really mapped from value 1) see: https://github.com/ufz/geotiff/blob/473ab941f80592ada6a226ec666d7e6e8f79c21b/geonames.h#L67

Question - are showing the strings enough (as below) or should we show the integers?

Thanks to Trent for this example. I have converted it to ASCIIDoc in the file annex-lunar.adoc

Open to suggestions about text strings vs. integers

Ted Could you please tell me where this file file annex-lunar.adoc may be found on the github?

I tried to find it in vain …

Thanks in advance Emmanuel

Ted, et al Unsure I understand correctly ..

In GeoTIFF spec. key values of type SHORT use the Geokeys referenced from GeoKeyDirectoryTag. key-values which are not of type SHORT are either: GeoDoubleParamsTag or GeoAsciiParamsTag (for strings).

What is this discussion about text strings vs integers ?

Emmanuel,

My bad. Forgot to synch with github… Lunar example is at https://github.com/opengeospatial/geotiff/blob/master/GeoTIFF%20Standard/standard/annex-lunar.adoc

All,

I am getting ready for multiple presentations next week at the ESIP meeting so geotiff has slipped to the back burner…
