rahmansunbeam Posted October 1, 2011 Report Share Posted October 1, 2011 I have been searching all over the web but couldn't find the answer. Please help me to solve these issues. A. I need to create a land use prediction map. This map will display the future change of use of land from calculating the past data. There are ways, first I learned about logistic regression method in Andes. Is there anything in Erdas or ArcGIS? Secondly there is Makrov Chain Analysis to do that kind of stuff. Anyone have a model I could use? B. This is quite an interesting job. I want to create several polygon shp containing same area. The polygon will be squares and will create a grid. Each cell contains same area. How this can be done? Is there any tool to do these kind of job automatically? Quote Link to comment Share on other sites More sharing options...
whocares1980 Posted October 1, 2011 Report Share Posted October 1, 2011 http://www.colorado.edu/research/cires/banff/pubpapers/94/ you can use this reference. It is very useful. You can use SLEUTH, however it is usually used with land cover NOT land use.... Land use prediction is a very challenging task... because 10s of variables should be modeled in order to predict land use. Quote Link to comment Share on other sites More sharing options...
mbn Posted October 1, 2011 Report Share Posted October 1, 2011 Hi, I think you can try linear regression analysis in EErdas, ban but forget arcgis either for regression analysis or for markov, i think only andes can do this. have try : change detection? it can be used in erdas/andes. Idrisi made : LAND CHANGE MODELER SOFTWARE FOR ARCGIS : http://www.clarklabs.org/products/Land-Change-Modeler-Overview.cfm. have you tried it? regards Quote Link to comment Share on other sites More sharing options...
gisadept Posted October 1, 2011 Report Share Posted October 1, 2011 Hi, Concerning question A: do you know how to apply a logistic regression? I did that before by means of Idrisi and SAS 9.3. If you want to know about it, just trigger me. Another modelling option the GEOMOD module implemented in Idrisi (you can search in literature for Pontius). As a starting point I can advise you to read the Help documentation in Idrisi for that module. Yet another option is the application of a cellular automaton. I guess there are software packages that can run such models, but I don't know them. Maybe you can program your own simple cellular automaton (search in literature for White & Engelen).

bdsmolla Posted October 1, 2011 Report Share Posted October 1, 2011 A. ArcGIS only having built-in OLS - Ordinary Least squares and GWR-Geographically Weighted Regression. however, ArcGIS 10 modelling improved tremendous with huge number of options to do anything you want but you need to make the algorithm. In ERDAS delta-que in fact do the change detection by comparing previous images. B. YOu can use fishnet function to do that. Quote Link to comment Share on other sites More sharing options...
gisadept Posted October 1, 2011 Report Share Posted October 1, 2011 Like bdsmolla already said, FISHNET is an option (I thought it was only for Workstation license; I may be wrong). Otherwise you can make use of ET GeoWizards LT. For complete use of this package you'll have to pay, but it contains also free functions (that always wil be free). One of the so-called 'Basic functions' is Vector grid. Perhaps this might be useful for you. http://www.ian-ko.com/ Quote Link to comment Share on other sites More sharing options...
rahmansunbeam Posted October 2, 2011 Author Report Share Posted October 2, 2011 Thank you everyone for your time and answer. http://www.colorado.edu/research/cires/banff/pubpapers/94/ you can use this reference. It is very useful. You can use SLEUTH, however it is usually used with land cover NOT land use.... Land use prediction is a very challenging task... because 10s of variables should be modeled in order to predict land use. Thanks. I've gone through the article and it is interesting. Can you explain SLEUTH bit more. Hi, I think you can try linear regression analysis in EErdas, ban but forget arcgis either for regression analysis or for markov, i think only andes can do this. have try : change detection? it can be used in erdas/andes. Idrisi made : LAND CHANGE MODELER SOFTWARE FOR ARCGIS : http://www.clarklabs.org/products/Land-Change-Modeler-Overview.cfm. have you tried it? regards Thanks. Yes, this is a wonderful extension. I hope mods will bring a c/r/a/c/ked version soon. I didn't tried linear regression, will it work? Can you refer a tut? Hi, Concerning question A: do you know how to apply a logistic regression?

Yes, logistic regression is my headache! But I know neither of Idrisi and SAS. I will search for celluler automation. A.

In ERDAS delta-que in fact do the change detection by comparing previous images. B. YOu can use fishnet function to do that. thanks. I have been wondering about the AG10 modelling for a while. btw, do deltaque generate prediction map? Yes it is a wonderful tool for change detection but i missed any function concerning that, i must have missed it. Please shade a light. Thanks again for the second prob. I guess i found that http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=create_fishnet_(data_management) Like bdsmolla already said, FISHNET is an option (I thought it was only for Workstation license; I may be wrong).

Please post any other suggestion which I could use. update: i found two more research article about land use/ cover prediction. The articles actually implemented the technology, which I need. http://nsgl.gso.uri.edu/washu/washuw99003/29-Allen_et_al.pdf http://www.jatit.org/volumes/research-papers/Vol23No2/3Vol23No2.pdf update 2: fishnet worked. B solved! :cheesy: Quote Link to comment Share on other sites More sharing options...

3dbu Posted October 3, 2011 Report Share Posted October 3, 2011 the good option is the module of IDRISI land Chenge modeler ...i did a prediction map and it work nice. regards Quote Link to comment Share on other sites More sharing options...

But I need to use either Erdas or AG. Quote Link to comment Share on other sites More sharing options...
3dbu Posted October 4, 2011 Report Share Posted October 4, 2011 i make a fution between idrisi and arcgis, make the analyst of change areas with idrisi and then make a model usind idrisi prbabilili of change area and use this in argis like indicator of the change using too another factor and try to do a prediccion of land use.
