This document records an email exchange between Simon Anastasiadis and Yun Liang on 25-May-2011
With regard to work on land use in rural New Zealand.

This was a larger project which several RAs were involved in. As a result of this, and restructuring of Motu's
 data library, not all the files that should be together are together. Suzi Kerr identified Yun Liang as the
 person most likely to know so Simon Anastasiadis checked with her.

Following this conversation, this document was created and a copy of the (incomplete) working paper
 'TowardsPredictingRuralLandUseInNZ_Yun.doc' was moved from:
 D:\Environment\Global Climate\Obj1_ModelBuilding\MS6 Endogenise stocking rates\Renees work\
 to this folder.
(D:\Environment\LURNZ\Data\Projects\Land use dataset\Version 2)

Hi Simon,

The structure of the Environment folder is completely different from when I was using it, and I only got involved in a very small part of the existing work quit a long time ago. I’ll try to comment on the files that I remember. 

1.	“D:\g\Research\Data_Library\Motu_Data\Free_Data\Rural_Economie_Database\Area by land use (calibrated to LCDB1, TA)\LURNZv2_LandUse_TA8104.xls”
This work was done by Jo Hendy, and documentation files also included in the same folder.
 The raw data and programs aren’t included, and the ReadMe file might be able to give you
 some clue of finding them in the current environment folder. 

2.	“D:\g\Research\Data_Library\Motu_Data\Free_Data\Enviromental_Raw_Data\Area by land use and animal numbers (TLA, County)\All - 0305 SNZ (ES) - Livestock and Land use TLA 1980-2003.xls”
This is the raw data from SNZ. We did use it in the land use project, so you might find
 it been mentioned in ‘TowardsPredictingRuralLandUseInNZ_Yun.doc’. I can’t remember what’s
 in the doc file. If it was the documentation file for the predicting job I’ve been
 involved, I must have told Wei pretty much all I know. 

3.	D:\Environment\LURNZ\Data\Projects\Land use dataset
…\Version 2\From Jo\Urban land\MASTER_96boundary.do listed the work I got involved. I have
 no idea of other folders. One of the listed do-file should have done the splitting of
 pasture area into dairy. Some of the preparation was done by GIS, and it also needed some
 matlab code, which was written by Jo Hendy as you could see within the file, but I’m not
 certain where those codes are. To be noticed, the method I worked on was only the initial
 stage, Jason Funk ,Jo Hendy and Suzi should have made some changes to the method, but I
 do not know anything about it.

Hopefully this helps. Wei should know many details about this work, as he has done some related work. But if he couldn’t help, Suzi would be the only one who knows the big picture of this. 

Best Wishes,
Yun

Subject: National land use at TA detail

Hello Yun

I am trying to find some data that was part of work you were associated with.
But the documentation and data might be separate.
(All the documents are on the SS)

The work related to constructing land use for the entire country at a TA level. It included separating pasture area into area for dairy and area for sheep & beef.

Would you please have a look at the file (documentation):

D:\Environment\Global Climate\Obj1_ModelBuilding\MS6 Endogenise stocking rates\Renees work\
TowardsPredictingRuralLandUseInNZ_Yun.doc

And tell me how it is related (if at all) to the following data:

D:\g\Research\Data_Library\Motu_Data\Free_Data\Rural_Economie_Database\Area by land use (calibrated to LCDB1, TA)\
LURNZv2_LandUse_TA8104.xls

D:\Environment\LURNZ\Data\Projects\Land use dataset\Version 2\Final datasets
RuralLUPanel4Sept07_docadj.xls

D:\g\Research\Data_Library\Motu_Data\Free_Data\Enviromental_Raw_Data\Area by land use and animal numbers (TLA, County)\
All - 0305 SNZ (ES) - Livestock and Land use TLA 1980-2003.xls

If you would also comment on the contents of the folder:

D:\Environment\LURNZ\Data\Projects\Land use dataset\

I have suspicions as to how these files fit together, but I’d like to hear your perspective before I check my suspicions against yours.


Thanks
Simon A
