how do i create a landslide suceptibility map using logistic regression with arcgis10.0?

sunnyedogbo — Sun, 14 Sep 2014 14:21:01 GMT

please i am final year undergraduate student

my project is to build a landslide succeptibility map using lodistics regression.

i have generated the following maps so far..

slopemap, hillshade, curverture, elevation, road buffers, river buffers of 100 - 500m , Aspect, land use land cover, ndvi.

all this maps after production do not have aribute table...

please i need a detailed explanation on how to use some of this data produced to produce a suceptibility map using logistic regression..

Thank you for your soonest possible reply..

There are no tables since most of the grids are floating point grids and only integer grids can have tables. Are you to perform a logistic regression on each layer (ie trend analysis with the logistic option‌ ) or using a combination of the grids? Are all these variables needed for the model or have a bunch of datasets been created which might be useful? What guidance were you given for this problem so that the people on the site don't advise you against the wishes or instructions of your advisor.

I think the logistic regression should be on all the layers so far I would

be able to produce a susceptibility map using logistic regression... your

help would be very appreciated ..Thank you very much...

I wouldnt mind if you would teach me how to to produce a susceptibility map using logistic regression i am a novice and most of the maps produced are from youtube tutorials thanks for

this maps were produced as a result of the articles I read...

I really need help with this thank you

You are providing no information for us to help you with. What articles? Why did they suggest those layers? and more importantly...what is your thesis advisor suggesting? You can't go blindly into a project like this without a firm game plan and some thoughtful consideration as to the types and appropriateness of the data you intend to use. After these are addressed, I am sure you will have some technical issues on how to implement your plan within a GIS. Good luck

attached are some of the maps generated...

and also some of the materials used....

my supervisor insisted i use logistic regression analysis for the analysis..

ild appreciate any help you could do to put me tru..

thank you..
