I have tables with Geometry (Multipolygon Shape field) in Mysql. I am able to successfully run Area and Centroid. Is there a way in MySql however to query the intersection between two shapes expressed as a percentage of one in the other?
As per comment/request I am pasting in two mutlipoint geometry fields as I cannot figure out how to create a shape based table in sqlfiddle to make that easier, my apologies.

I have a set of data at which I would like to fit a curve to. However, I'm having difficulties with finding the right equation type. I'm guessing it's a type of sigmoidal function.
I have tried several forms, but none of them seem to fit sufficiently, see for an example below. I add here below the corresponding X and Y values. Can anybody help to find the right equation?
Thanks!

Looking at data with a log plot, the tail seems to be compatible with an exponential decay:
The first peak can really be anything. A Gaussian fits fine, as well as the sigmoid you suggested. Here's a fit using the sigmoid + exponential decay:
import fitwrap as fw
def f(x, A=0.5, x0=5, B=1, t=20):
first_peak = A * (-1/(1 + np.exp(-(x-x0)))+1)
decay = B * np.exp(-x/t)
return first_peak + decay
fw.fit(f, x, y, plot_range_x=(0,200))
fit results:
A: 0.71395 +/- 0.00282 (0.4%) initial:0.5
x0: 3.4017 +/- 0.0126 (0.4%) initial:5
B: 0.33547 +/- 0.0026 (0.8%) initial:1
t: 14.225 +/- 0.116 (0.8%) initial:20
I am using St_contains to find whether a point is in polygon, but the result seems to be inaccurate. If a point is not in the polygon, St_contains will still return 1.
here is my code
SET #i = ST_GeomFromText

I have been searching for a long time and still don't know where the problem is. Please help me to check it out. Thank you in advance.
I am trying to buffer a handful of geometries and then run the same buffer as a negative. But am getting unexpected artifacts in the responding geometries.
Running a positive buffer (original geom is orange):
Running a positive and negative buffer (original geom is orange):
I can produce slightly better geometries by running the first buffer with side=left join-mitre but it's still not perfect and the geometry from the second buffer is messed up as a result.

Just add some 0 and change parameter of st_buffer

There is j:SearchFilterForList
What i want to know is when its work (type some text on the filter textbox), how to find filtered list length?
Thankyou
Just use the new "length" property just recently added. Tour de Jewel was updated as well showing the use of this new bead property in the List examples.
<j:Label html="{'list filtered length: ' + filter.length}"/>
<j:TextInput>
<j:beads>
<j:TextPrompt prompt="filter list..."/>
<j:SearchFilterForList id="filter" list="{iconList}"/>
</j:beads>
</j:TextInput>
Notice that the filtering performed by this bead is only visual, and the underlaying dataProvider is not filtered itself. To get a filtered view of the dataProvider you should use ArrayListView API, that is similar to flex ListCollectionView with filterFuncion.
I have a KML file and made a fusion table out of this.
In this fusion table there are a lot of polygons split one per row.
One of these rows contains following polygon:

The problem with this polygon is that is it not showing up on the map?
But when I preview only this polygon it is :/
Does anyone experienced something similar or know a solution for this?
Thanks in advance!
You have some inner polygons that look like lines to me. Removing those might help as well as simplifying the outer boundary. KML with winding direction calculations
Remove the <innerBoundaryIs> tags and it displays for me
