GeoTiff Convert to Shape File

Do I understand you want to convert the rastercells to points or polygons? This can be done but will result in a lot of points / polygons. About 5.000.000 for this raster.

Steps how you can do this:

• Reader or FeatureReader to read the raster.
• RasterCellCoercer to convert the rastercells to points or polygons.
• AttributeCreator to convert the raster cell value to attribute. In this case _band{0}.value.
• Writer or FeatureWriter to write the result to shape.

give me null Values

Correct. The values are in the list "case _band{0}.value" so you must create an attribute using the AttributeCreator where value is case _band{0}.value.

You can see this in the Feature Information window in the Visual Preview or Data Inspector.

still not getting it

Attached workspace demonstrating this.

work perfectly fine

can we merge features with similar category

as in one multipolygon for each category

it's like each pixel has been inserted separately as a record

this doesn't seem right

adjoining features need to be merged as a single polygon

that way, they will represent a single region

Merging adjoining polygons with similar attributes can be done using the Dissolver.

but i need in polygon

i am new and i have no idea how can I do that

I think the best advise I can give is to work through the FME Academy first, to get up to speed working with FME.

i am but atm this work is in urgent situation

Hi @asadamjad​ Currently in your AttributeCreator, you are assigning "_band{0}.value" to the New Attribute parameter. Instead of assigning it to the New Attribute parameter, try assigning it to the Attribute Value parameter. You can then assign the name of the attribute in the New Attribute parameter.

Hope this helps! - Dan M
