Maps from images

Hi Guys,

 

We have Australia Maps updated as images, they are from level 1 to level 6:

Level 1 = 24 images

a1_1_1.gif

a1_2_1.gif

…

…

a4_6_1.gif

 

Level 2 = 586 images

a1_4_2.gif

…

…

a21_30_2.gif

 

Level 6 = 2190 images

a686_1809_6.gif

…

…

a1172_1503_6.gif

 

Any ideas how to use those images with Map Server?

Please ask for any kind of clarification

 

Regards

 

 

I guess these are images at different scales and pixel size.

 

I would create a tile index for each level and then turn each level on and off at the appropriate scale.

 

Regards Ian

Mohamad,

 

I have assumed that each level of images is the same area, but at a different scale.

 

So using the gdaltindex tool (in the \ms4w\tools\gdal-ogr directory), you can create a tile index shape file.  This file can be used in the MAP file to load the appropriate image.  Then using the MINSCALE and MAXSCALE setting in the MAP file you can turn the different levels on and off at the appropriate scale.

 

Each of your imagery levels 1 - 6 will require its own entry in the MAP file and have its own tile index shape file.

 

An Example is:

 

LAYER

            NAME linz_orthos

            GROUP "IMAGERY"

            TILEINDEX /gis-data/linz-ortho/linz-ortho

            TILEITEM "LOCATION"

            TYPE RASTER

            DUMP TRUE

            MAXSCALE 500000

            MINSCALE 3000

            PROJECTION

                        "init=epsg:27200"

            END

            STATUS OFF

            CLASS

                        NAME "LINZ Aerial Photos"

            END

END

 

 

LAYER

            NAME ncc_orthos

            GROUP "IMAGERY"

            TILEINDEX /gis-data/orthos/napier_2009

            TILEITEM "LOCATION"

            TYPE RASTER

            DUMP FALSE

            MAXSCALE 3000

            PROJECTION

                        "init=epsg:27200"

            END    

            STATUS OFF

            CLASS

                        NAME "NCC 2009 Aerial Photography"

            END    

END

HI Ian,

 

I become more optimistic after what I read what you wrote.

Your assumption are in place, each level of images is the same area, but a different scale.

 

As I understand ,all the tools exist for the purpose of usages of those images in MapServer implementation.

 

Before Asking more questions, I would like to ask this stupid question to make things clearer in my mind: Do you think we can use those images to build a Mapping server?

 

 

My next question is: is there any tutorial or document?

 

Thanks

Mohamad

Mohamad,

 

For documentation / tutorial have a look at the MapServer website (http://www.mapserver.org/).

 

Yes, MapServer will read the GIF images, but you will need the world files (WLD).  So yes you can build a MapServer to display and publish the images.
