Troubleshooting Layers Disappearing on Zooms

JanisBurall

I am using AE Desktop Build 1700 on several computers which pass the system requirements check. I have about 10 layers of water & wastewater (manholes, lines, hydrants, valves, etc.) in a fgdb, added as .lyrs and saved in the .nmf. The data is not complex, not a geometric network. I have cleared caches, simplified symbols and removed groups, folders, and layers trying to fix a problem I experience on mulitiple machines of one or more layers not updating after a zoom. For example, sometimes the layer does not draw but its labels do, or, sometimes a layer will remain thick and fuzzy (not refresh at the new scale) though other layers refresh. I set various scale depencies ArcMap where I created the layers, but not for layers to turn off when zoomed in! I have about ten other layers such as parcels, district bounds and address pts also saved in the .nmf. The extents of my local data (not the base maps) are only about a couple square miles. Can you give me some ideas for troubleshooting?

Also should mention that all my data and use is 2D, and on the machines where the problem is most persistent, the program is frequently hanging, especially after me testing with frequent zooms, turning layers on and off, clearing layer caches and map caches. The map cache size is about 240 MB.

Hi Janis,
Just a thought:
We also had trouble with layers not refreshing on zooms a couple months ago. Other users also reported the problem on this forum. Turned out that ESRI's cacheing didn't really do what it was supposed to do.

The workaround was to check the option for refreshing a layer at a regular interval, even if the data never or rarely changes.

I went through all our map content files, selected the third option and set each to refresh in 1, 3, 5, 7 or 9 hours. Thought prime numbers might avoid layers refreshing all at once.

In any case it solved our problem.
That was in 1500. Haven't checked if ESRI solved the problem for 1700.
Anybody (ESRI?) know if caching now works as advertised and I could safely change some static layers back to hardly or only once refreshing?

JanisBurall

Thanks for the suggestion, Darryl. I will try it and report on how well it solves the problem.

Wow, thank you for the refresh options hint in the layer properties! I was updating my video card driver, trying to create my layer packages on network drives vs. local drives, eliminating scale dependencies, trying more simple symbology, etc. It didn't seem to matter, even for a very simply polygon layer symbolized with a flat color and no labels.

I'm using build 1700, so nope, they haven't fixed what looks to me like a bug. The good thing is that once you set the option, the scale dependent visibility for the layers and labels I set in ArcMap when creating the layer packages seems to work in ArcGIS Explorer.

Now, if the display in ArcGIS Explorer would only tell me the relative scale...

I am trying to reproduce the problem. Using ArcGIS Explorer 1700 and this layer package. http://www.arcgis.com/home/item.html?id=327bf28f53114f5b82a22a4e6746e42f

I am not seeing a problem with the display of the data. I just add the layer package to the default map.

For those seeing a problem can you share a layer package that shows the problem, or use the one referenced and see if you have the problem with it?

Or is this perhaps a problem related to referencing data that is changing (being edited) and requires cache to be cleared to see the latest edits?

Thanks,
Mark

I have an occasional hickup like this and it seems to me like it is a cache issue. We stream layer packages from a networked drive and on occasion at a certain zoom level part of the drawn data will be missing or will not show up at all. I have confirm this is not due to a newly edited .lpk. I am using 1700. The only way I can fix this is by deleting all cache or by just setting the map to refresh at intervals or when it opens. No big deal but it does kind of defeat the cashing purpose.

I think the reason could be a lot of things though. Network hickup, memory issues. Attached is a pic of part of the parcel layer missing at a certain zoom.

Mark, I can send you a parcel package layer that has this problem but I don't want to post in on the net. Can I send via email?

Thanks.

MarkBockenhauer

Looking at the picture I don't think the problem is specific to your dataset, I would think that I would see the problem with any parcel data.

What coordinate system is your data in?
What coordinate system is your map in?

What data type (geodatabase, shapefile, SDE etc..)?

Thanks,
mark

DustinDunnill

Hey Mark,

I am using a shape file in layer package .lpk format streamed from our County network drive.

The parcel .lpk data coordinate system is NAD_1983_StatePlane_Hawaii_2_FIPS_5102.
Using the same coordinate system for map with GCS_WGS_1984 and Transformation NAD_1983_To_1984_3.

Thanks.

I'm having this same issue in ArcGIS Desktop 10. The feature class (polygon) layer is visible only when at full extent. As soon as you zoom in, it disappears. I've tried recreating the feature class (i.e., redigitizing the polygons), but the new layer does the same thing. The coordinate system is correct. I've tried bring the layer into an established workspace and an empty workspace---same problem.

Is there cache refresh options in Desktop 10? If so, where can I find them?

Any help is appreciated!

BrianLocke

I know this might sound like an easy fix and may be silly to mention but have you tried to check what the visible extents are in ArcMap 10???

further. I too have had the same issues with cacheing lyr's alot of the times I have found myself deleting the caches and have had them come back for a usable amount of time but then ultimately they dissapear again.

DustinDunnill

Thought it would be good to update this with what I have found as an easy fix for this for the time being. A right click on the layer in the contents window then a left click on "refresh" seems to clear any hick ups for me until the next disappearance, then a refresh is necessary as needed.

Hopefully this cache issue can be iron out in the future. Sounds like it will.

Can anyone tell me if this issue has been resolved? I have just updgraded to ArcGIS 10.1 and have created mulitple personal geodatabases with layers that are not displaying when using the zoom tool. It is not clear from me on the thread how to address this issue.

JanisBurall

Hi, kcwoodall. I have been frequently clearing the layer caches in AED and varying the layer refresh times as suggested in previous posts. I continue to do this through our upgrade from build 1750 to build 2500. It is a lot of maintenance, but it seems have cleared up the problem.

kcwoodall

Thanks for the quick response. I do not run AED but could look into it, my machine would support it. Do you know if there is a way to vary the refresh times in ArcCatalog? I am supporting folks around the state that do not all run ArcInfo but need to edit these layers in personal geodatabases and it would be great to have a permanent fix for them. BTW - seems to work ok if I export the files to shapefiles - problem goes away.

JanisBurall

This issue was happening to me while I was working in ArcGIS Explorer Desktop in 2013. I actually don’t use that product anymore, so I don’t know if it was ever fully resolved. I have not had it occur in straightup ArcGIS 10.x (as opposed to Explorer). Sorry I cannot be of more help. My suggestion is to contact ESRI support to help you troubleshoot the problem. Good luck!
