Greeting,
In an effort to make the transition from ArcView 3.2 to IA CS2 I am exporting my AV data as an AI file.

This project will be to show the area of the Dunkard Creek Watershed with the following layers:

Watershed boundary
State boundary

All streams
Monongahela River

Major Roads
Other roads

Towns

State Game lands ( PA )
WMA ( WV )
Mason Dixon Park

I have exported two AV layers thus far: Streams and Roads

I opened up the streams .ai file in AI CS2
I then:
Set the page layout to 18x24" LS
Changed the Docuement color mode to RGB

I then opened up the roads .ai file, selected all and copied the layer.
In the streams .ai file I created a new layer.
I then copied the roads layer and pasted it in front of the streams layer.

They both registered.

So far so good.

When I started checking areas closely I noticed there is much overlapping of the two.
It appears the stream layer is now intersecting the road layer in many areas. This is not the case in AV.
See the PNGs at:
http://mbreiding.us/PNG_Dunk_Crk_WS/

Dunk_creek_WS.png is the project area
stream_road_overlap.png is a screen shot showing and area of overlap.

Did I do something to cause this?
The are so many overlaps I cannot see any practical way to edit them out.

What say you all?

-Mike

I new I would forget something.

I concantenated both road and stream layers ( default settings), and simplified both paths to 98% for smoothing.

Mike,

Any chance of sending me some sample files (shapefiles) so I can have an 'independent 2nd opinion' for you (although it'll probabely have to wait until I get back home, on monday). Feel free to email them to hans-at-redgeographics-dot-com

It seems to be a problem related to Arc's Illustrator export.

On a side note, I merged the two topics you started, to keep things cleaner.

Greetings Hans,
I will email you the two shape files I exported from AV3.2 for use in AI CS2.

The entire project is here:

http://mbreiding.us/av_2_aics2/

The project path is in the APRs is: c:/dunk_oct/dunk_oct-files/

Thanks very much,
-Mike

Did they register prior to this? The two layers would simplify differently, which may cause the mis-registration you see?

I checked and the were overlapping pre-simplifying

Is this a possibility...... that the original layers in AV are in different projection/datum? I can't remember from my brief AV experience, if the layers are reprojected in a mapview. I have seen data sets here with one layer in Nad27 and other Nad83 which might result in a shift of a couple hundred metres if the layers weren't reprojected before exporting.

So you might check that the stream and road layers are both the same datum (eg:NAD83).

They are all NAD83 Zone 17 1:100,000.

They look fine in AV. It is when they are exported to AI the problems shows up.

Mike,

Can you post the orginal shapefiles, and I will try to do an export on my end to see if I can reproduce the problem.

Mike, I found your zip file.

Here is an AICS2 file exported with the two layers. Looks the same as it did in Arcmap 9.? no weird overlaps that were not present in the original data.

Pre-Arcmap 8.X the illy export was notoriously bad...hence how Mapublisher became such a necessary product. The new generation is very robust and as close to WSIWYG as it gets.

Let me know if you see any weirdness in this data.

Hi Martin,
Attached is a screen shot of the files you sent when opened in AI CS2.
The overlap is not as significant, but what are those reddish-orange segments?

Also, when i opened the file I got a warning dialog box about certain fonts not being available. This is weird since there were was no text, right?

If I cannot get this resolved soon I am going to have to give up on using AI CS2 to work on exported shape files. I would really like to make this transition for the concatenation and smoothing options alone which are available in AI CS2, but not in AV3.2.

Thanks,
-Mike

Mike,

I symbolized different road classes differently which explains the different colors, I also labelled the roads based on the label attribute which explains the text...the overlap problem seems to be with your data. The export to illustrator is not modifying the data at all...i see no difference between the display in ARCmap and the display in the AICS2 file after export. The overlaps are there in the GIS display.

BTW doing a dissolve operation using the geoprocessing wizard in AV is the same as concatenating, you can also find some tools like Ianko's edit tools http://www.ian-ko.com/ which will allow you to do those geoprocessing GIS tasks in AV.There is a huge amount of free custom tools for AV as a result of Avenue programmers writing cool little scripts for many years...spend some time on the ESRI website doing searches for scripts for your version and you will likely find a free utility that does what you want. As for the export, like I said it is flawed from AV3.X and it may be making it worst, but from ARCMAP I do not see any difference between the data as I see it on screen in ARC and as it appears after export to AI.

Hi Martin,

Looks I will need to find another way to export to AI other than AV 3.2.
Your export with ArcMap show much less overlap of the two themes.
I still seem to seem some overlap in the AI files as apposed to the data in the AV view,
but that may be just a matter of scale, and stroke weight. I really don't know.

I have used dissolve before but always just for segments of the same road or stream , etc. I never though about doing a dissolve on the entire theme.

I have perused the Arc Scripts site a number of time and use several all the time.
I often do not understand what they are for or how best to utilize them.
I am a pretty light weight user and do not spend a lot of time using AV because of the limited number of projects I get involved with.

Thanks,
-Mike
