iMap user questions
Q. I can't find the map layer I want to see.
A. There are currently more than 80 map layers in iMap collected into 13 thematic layer groups. When you open the Layer List panel you see the layer group names. Click or tap any one of them to expand a list of individual map layers that are collected in that group.
This PDF document lists all of the layers by name as they appear in iMap (organized by layer group on page 1 and alphabetically on page 2).
Q. I see the map layer I want to view in the Layer List, but it doesn't appear on the map.
A. In order to be visible, an individual map layer needs to be checked on AND the layer group that it is part of also needs to be checked on.
Q. I want to be able to zoom in more to see more detail. Can you make new iMap do that?
A. New iMap has fixed-scale map zoom levels and each zoom changes the map scale by a factor of two. We have added one larger-scale zoom level since iMap's launch in April and we don't have any immediate plans to add more. However, the current maximum zoom level corresponds to the full resolution of the 2013 aerial imagery basemap, so zooming in more would not reveal any additional photo detail. The other aerial photo basemaps, which represent the years 1936, 1998, 2000, 2002, 2005, 2007, 2009, and 2012, have not been prepared for display at the current maximum iMap zoom level. We are planning to add the maximum zoom level to those aerial basemaps which include imagery that is of a high enough resolution that additional detail will be detectable at maximum zoom.
Q. I'm trying to use the Print tool, but I get an error every time I try to create a map print.
A. Try reloading iMap. In our testing, this has fixed such problems.
Q. The printed map extent does not match the viewer map extent.
A. Select the “Advanced” options on the Print panel, under “Map Scale/extent” select “Preserve map extent,” and then try a new map print.
Q. The basemap doesn't appear in my print map.
A. This may occur when the map view is at the maximum zoom level. Select the “Advanced” options on the Print panel, under “Map Scale/extent” select “Preserve map extent,” and then try a new map print.
Q. I created a print map and it shows an area entirely different from what I expected, or it shows a print map I created earlier instead of the one I just created.
A. We are researching this occasional glitch. If this happens, please try creating your print map again. If you have any print maps in your list, you might want to clear them using the “Clear Prints” button.
Q. When I launch iMap all I get is a blank screen. Why?
A. We have had reports like this from some users of Internet Explorer and it is usually due to a security setting in Internet Explorer. The problem can usually be solved by opening the browser's Internet Options, selecting the Security tab, and adding the iMap URL (http://gismaps.kingcounty.gov/iMap/) to Trusted Sites. One must have administrator privileges on the computer in order to make this change. Alternatively, try different web browser.
Q. I no longer find links to the Assessor's Report and the Districts and Development Report.
A. If you do a basic search for an address, iMap will zoom in to a location and a pop-up will confirm the address. But you must then click on a parcel in order to see a pop-up that displays information about that parcel, including the familiar links to the Assessor's Report and the Districts and Development Report. Alternatively, if you do an Enhanced Search for a parcel, the result displayed in the Enhanced Search panel will include two buttons, one for each of the reports.
