Wow, Thank you
Todd. That hit the nail on the head. I can do that. Thanks so much….. From: Todd Fagin
[mailto:tfagin@coordinatesolutions.com] KC, By example, say you have a school district layer and a wells layer
and you want to find all wells that are within the Mid-Del school
district. You actually have to do two queries in ArcMap:
Your other queries will likely take similar form. Depending on the
spatial relationship you’re trying to find and other criteria. You ask,
for instance, where your pipelines cross. Do you mean where the pipelines
cross other pipelines? If so, are the pipelines all in one layer or
different layers? If different layers, you can simply do a select by
location/intersect. You can also do a spatial query where a layer
intersects itself. However, in order to do this in ArcMap, at least one
feature must be selected. So, if you want to know all pipelines that
intersect pipeline A, you would do a select by attribute query to first find
all pipeline features meeting the criteria of being pipeline a, then you do a
select by location query in which you select features from pipeline that
intersect the selected features in pipeline. Finally, if you are wanting to know where your pipelines cross a
different layer (e.g. something from StreetMap USA), a Select by Location,
Intersect should work. Make sense? Todd Fagin Coordinate Solutions, Inc. 2804 NW 18th St. Oklahoma City, OK 73107 405.740.4324 (voice) 904.471.5548 (fax) www.coordinatesolutions.com From: K C Spain
[mailto:kcspain@stephenspro.com] Hello and Happy
Holidays. I’m sure as most
of you know, I am still quite an amateur at this. I haven’t had to deal with
queries until now and I feel these questions are going to be difficult for me
to put into the right words, so bear with me. I have learned recently that my
‘higher-ups’ wish to implement some querying in my GIS. For example, Wells
(points) within ‘specific’ school zones (polygons). The school zones are in one
layer but are identified with unique values, ‘name’, as are the wells. Also, I
will be needing to query where my pipelines cross, in Streetmap USA, ‘Streets
and Highways’, ‘roads’, ‘railroads’, ‘water’ etc.. And does anyone know if and
how these queries would carry over to my web application? I have looked at the
Query Builder and I am not seeing exactly what I’m looking for. If anyone could
shed some light on the subject for me or point me in the right direction, I
would greatly appreciate it. Thanks…. K.C.
