I'm using Arc 10 and want to know how to upload tiles and a dataset (polygons). Anyone still familiar with this!?

Insert a new empty dataframe don't add any other data.

Click on the Add Data Button (yellow plus)

Navigate to the folder that you unzipped the *.tif file too (all the other parts are needed)

Add just one tif file and nothing else

Does the file load?/show? If not, right-click on the file's name in the table of contents of the map and select zoom to layer Does it show now?

OK. I:

Opened ArcMap10

Inserted new dataframe

Added 1 x tif file - it does not appear that I can insert the constituent

parts of the folder (tif tfw aux.xml and ovr) - just the whole file

The following message comes up:

If I press OK the tile has loaded - but of course the scale is not there.

Maybe the tfw files (worldfiles) aren't correctly? You could open them with a editor and have a look what's written there?

You need information about the coordinate system of your raster data.

World file - Wikipedia

DanPatterson_Retired · ‎08-02-2017

an image... in your case, a *.tif ... can have many parts that is why you use the Add data button, it does the figuring out of which bit(s) to use.

1 I just want to ensure that the images are good... ie they load ... so far so good

2 What 'scale' they have depends on whether they have real world coordinates or not...

If the image is just a bunch of pixels without any guidance as to the pixel width and height and some location parameter

(ie top left corner perhaps ... there are other ways

3 If you lack this information, then you have a 'picture' and you will need to get or confirm the information in step 2...

That information may be contained in the *.tfw file or other bits

When you can assemble what you have, report your findings so others can move you forward

If you use this data or similar:

1:250 000 Scale Colour Raster support

You could download the tfw (worldfiles) files on this page?

As Dan mentioned, the .tfw should contain info about the spatial reference. It needs to have the exact same base name as the tif (i.e. same, except the extension) and needs to be in the same folder and the .tif. As an example. my .tfw (in an Albers projection, so yours will look different

edit: might help to see one of your .tfw files...or if you can zip all the files for one of your images and upload, it may help others troubleshoot. Even a .zip may be too large to upload to Geonet (not sure of the limit offhand)

OK the file names are the same (NZ01.tfw = NZ01.tif etc). But I can't get

into the tfw files to alter them. A web search suggests Arc Reader as a

program to open thje tfw file but there doesn't appear to be a download for

ArcReader 10 (I am presuming the version has to match the GIS version (Arc

Reader 10 for ArcGIS 10 and so on).

Cheers,
