SUM:python point 2 lines

2008-12-01T06:40:40Z

Original problem:
I have ArcGIS 9.2, service pack 6, python 2.4. I have a script I'm running from pythonwin that is based on the example in the help under the topic "Writing Geometries". Basically, the idea is that you have an ID, X, Y. The ID indicates the line the points are to be grouped on. So you might have: 1;x;y 1;x;y 1;x;y 2;x;y 2;x;y The result is that the first 3 points form line 1, the next 2 line 2 and so forth. Everything works peachy if the x and y values are some projected coordinate value. As soon as those values are decimal degrees, the line gets simplified so that it doesn't go through all the points. Has anyone run across this, and how have they fixed it? I have a similar script that I run in VB that is fine. It's only when I go to python that I have this issue. I converted my lat/longs to utm coordinates and the line goes through every point. Assuming it's some sort of rounding issue, I made sure to define the spatial reference of my output shapefile.

This exact same script works in ArcGIS 9.1, python 2.1 with lat/longs.
Solution:
I could never get this to work in 9.2. Someone suggested defining the XY tolerance and/or the cluster tolerance. These are options to define in 9.2, but they had no affect on the results. I was working with decimal degree data, carried out to 6 decimal places, and it appeared as if it was not reading all the decimal places. Once I got 9.3 installed, I could get my python script to work just fine by defining the spatial reference of the output shapefile as geographic. It appears that once it knows it's geographic, it knows to carry things out more decimal places. Again, nothing I tried worked in 9.2.

cheers,
VeeAnn

Grid cell values of two different floating point rasters

2008-11-28T20:45:44Z

Hi all,

I have two very large global data rasters in grid format, each has
about 10 million cells. One is integer and the other is floating
point. Now I have to:

1. Get the cell value of every cell in each grid and export those
values into a table. I know for the integer grid I can convert it to a
polygon and get the cell values from the "gridcode" field, but how do
I get the cell values from the floating point grid, especially when it
has 10 million cells?

2. After I get all the cell values of both grids, I need to make a 2-D
plot of these values against each other. For example, value of cell #1
from the floating point grid (X axis) against value of cell #1 from
the integer grid (Y axis). Is there any way to know the cell value of
a particular cell, or to make sure that when I make the 2-D plot, the
X-Y values are referring to their matching cells?

Thanks a lot!

Ophelia

simplifying polygons

2008-11-27T08:32:18Z

Hi all

I often need to reduce the size of a polygon shapefile by simplifying
i.e. reducing the number of vertices. I find mapshaper
(http://mapshaper.org/) seems to be much better at the job than ArcGIS -
the latter leaves me with slivers. However, a major problem with
mapshaper for me is the 16MB limit - my files are often bigger than this.

Does anyone have any advice of a better way to simplify in a simple way!

Thanks

nested loop in Python

2008-11-26T14:09:00Z

Dear Fellow,
My questions are:
We have landuse maps of various periods, Shapefiles (Polygon): Parish.shp and Parcel.shp
Each parish contains several parcels. We need to get a detailed landuse map for each parcel.
We have tried to intersect the landuse.shp with the parcel.shp- the parcel.shp is too big.

After the intersecting of landuse (‘1’ and ‘0’) with parish- some parishes are totally landuse type ‘1’ or landuse type ‘0’. – other parishes contain both land use type ‘1’ and landuse type ‘0’—for these parishes we need to process further to see the landuse type for each of the parcels that the parish contains. We will have more than 2 types of landuse in the more recent land use maps.

The alternative way is to process the landuse.shp and parcel.shp directly- how could I do it by Python script?

What I think is that look through each parish to test whether it has more than one landuse type, if not assign the landuse to the parish, else intersect with land use and assign each parcel a landuse type, Once all parcels populated dissolve.
Thanks

Larry

How to export a clipped map ready for PowerPoint

DATA: Benthic Substrate off of British Columbia

2008-11-25T15:33:48Z

Greetings,

I am carrying out benthic terrain modelling of the British Columbia coast
out to the 200 nm limit of the Exclusive Economic Zone. One of the inputs
I need is a substrate layer. I have all of the bottom type information
from all of the Canadian Hydrographic Service charts of the area, including
the smaller scale overview charts. However, bottom quality information in
deeper waters is sparse indeed and speaks about only a few areas.

I am next going to down load the NOAA charts for Washington and Alaska with
the hope that I can extend any substrate information at least some way
across the southern and northern boarders into Canadian waters.

Does anyone know of deep water substrate information?

Regards,

Calculating point distances based on attribute value

how can I calculate the distance between points in a shapefile that share the same attribute value? In other words, my table has a field named "ID". I would like to run a calculation on that field and get the distances between all 5 points whose ID = 5089 and then all 20 points whose ID = 5090. I hope I'm being clear enough...

I would like to intersect the land use and the parish first, then test
whether each parish has more than one land use types, if not assign the
land use type to the parish, else select the parcel (from the cadastre

ArcSDE - basics - data updates / locking

2008-11-20T03:50:49Z

Hello all,

I am at the design stage of an ArcGIS server implementation (fully read-only - i.e. no data editing) that will use Oracle as the RDBMS. My SDE knowledge is fairly limited and I can't find answers to my basic questions in any help or on the forum.

We need to update the data sets in the system while it is in use. Some point datasets will be regularly pulled in from other databases (via scheduled geoprocessing scripts). Others such as background maps (raster) and point data will need updating less regularly. The system is required 24x7. What strategies are available to avoid locking problems and down-time?

I have come across having two copies of the database and updating one while it is not in use, then swapping the one in use and updating the second. Are there other options?

Thanks,
