I usually use numpy for my processing but I'm trying to make the most of the power of GeoPandas for my spatial data. I have some point data (shapefile) and a vector grid (fishnet) as a separate shapefile. I would like to get the points that fall within each vector grid and then do some basic statistics on them (e.g., average). Each point has an X co-ord, y co-ord and a Z value. I would like the mean value of each that falls within a grid cell. All answers I have seen so far are either testing if one point is within a polygon, or does not go further and calculate statistics, only returning a boolean array. From  I got this piece of code: point = geopandas.GeoDataFrame.from_file(pointfile.shp) poly  = geopandas.GeoDataFrame.from_file(gridfile.shp)  pointInPolys = sjoin(point, poly, how='left') grouped = pointInPolys.groupby('index_right')  but as I'm pretty new to Pandas I'm not sure how to get at the data in this group (or really what a group is) so I can calculate the mean value of the points. How do I get the data and perform basic statistics on it?
I am trying to estimate summary statistics of points located inside a polygon. Each points in the point layer is associated with N attributes. My target is to summarize (say mean, min,..) the attributes of points located within a polygon and populate the attribute fields of the corresponding polygon.   I am looking for a solution using GeoPandas or other Python libraries.   import geopandas as gpd    gdf_points = gpd.read_file('/path_to_points.json') gdf_polygon = gpd.read_file('/path_to_polygons.json')  dfsjoin = gpd.sjoin(gdf_polygon ,gdf_points)   Now, how can I summarize the stats for each attribute in the point layer and add it to the polygon shapefile? Which function can I use?  I am looking for something that is functionally equivalent to ESRI ArcGIS  with
setSystemUiVisibility(SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION) does not work When I open the game, the screen stays at the Mojang sign and then crashes. It has something to do with my texture pack, but I can't start the game to change it and it won't let me delete the texture pack folder alone.  I've already deleted the bin and resources folders in the minecraft folder and downloaded the game again. I opened it but the same problem was still there.  How do I properly perform a clean uninstall of the game? Draw a bivariate normal distribution in TikZ For a small class I want to draw a bivariate normal distribution and show where the means from the two variables meet in the space. Has anyone done this in TikZ? Can anyone please help me with my problem regarding my WordPress left hand side admin menu. I want it collapsed at all times, how do I do that?  Well, I'm creating a WP Multisite so I want that menu bar to be always collapsed at all times.  Any help would be appreciated. Looking for code or if plugin exists, should be fine, too. Thanks.

I was able to post in chat with less than 20 rep by joining 20 sites I joined 20 other sites (out of the many) and even with 1 rep was able to post in any of the chatrooms. For example: In ELL, I have just 1 rep and have posted messages in its chat.  ell.stackexchange.com/users/18923/lamart This seems like a bug because I should have needed 20 rep to post. . EDIT: From , I got the idea to make this edit. To reproduce this bug/error:  Create a new SE account. Use it to make an account here. You will get 1 default rep. Choose a random SE site and use this account to get 1 rep on that random site. Repeat the above step 20 times. Now you have 1 rep on 20 network sites but the net SE rep is 20. Go to the ELL chat and ping me. (important step)  From my comment: I have now got 40 rep since people voted this question up. Initially I had net 20 rep gained by creating 20 accounts on 20 different SE sites. Those default 1rep added up to get me to 20rep and I was able to chat. The link says one needs 20 rep in any of the SE site to chat in &quot;all the other&quot; category chatrooms..... but I did not have 20 rep on ELL at that moment. How to create a  tag with Javascript? I'm looking for a way to insert a &lt;style&gt; tag into an HTML page with JavaScript.  The best way I found so far:  var divNode = document.createElement("div"); divNode.innerHTML = "&lt;br&gt;&lt;style&gt;h1 { background: red; }&lt;/style&gt;"; document.body.appendChild(divNode);   This works in Firefox, Opera and Internet Explorer but not in Google Chrome. Also it's a bit ugly with the &lt;br&gt; in front for IE.  Does anyone know of a way to create a &lt;style&gt; tag that   Is nicer Works with Chrome?   Or maybe   This is a non-standard thing I should avoid Three working browsers are great and who uses Chrome anyway? Can I invoke Google to check my robots.txt? I read the answers in this question, but they still leave my question open:   I didn't find a way in the Google Webmaster Tools to invoke a re-download of my robots.txt.  Through some error, my robots.txt was replaced with:  User-agent: * Disallow: /   And now all my content was removed from Google search results.  Obviously, I'm interested in correcting this as soon as possible. I already replaced the robots.txt, but I can't find a way to make Google update the cached version. When a ball is tossed straight up, does it experience momentary equilibrium at top of its path? This question has been asked many times all over the Internet and answers can be found on places such as yahoo and ask.com, but I'm not satisfied with those answers and I don't trust the validity of those places.  This seems like a more appropriate place to ask.  So, here's my train of thought and I would like to ask you if you think I'm right or wrong.  Even though most of the answers point to the fact that the ball does not achieve equilibrium because the force of gravity is constantly acting upon it, thus causing an acceleration, I still think there's a moment of equilibrium and here's why:  When the ball is traveling up, it's accelerating towards the ground and eventually reaches a point at which its speed reaches 0.  At this moment, isn't the reason the speed is 0 is due to the fact that net force is 0?  The force that made the ball travel in the upward direction was canceled out by the gravitational force.  So, the sum of forces at that brief moment is equal to 0, otherwise the ball would be moving.  I don't think gravity is the only force acting on the ball at that moment, since the throwing force was acting on it as well, until both canceled each other out for that brief moment.  Am I right or wrong? If one obtains results in one area of a field (say during an MSc thesis) before deciding that one is not interested in making a career in that area, should one take the time (as a PhD student) to get make those results publishable, or is it better to focus on the new area? How do I make Chromium use Flash from Google Chrome? Now, that Adobe has stopped issuing new releases for Linux desktops, the only option for users is to use Google Chrome, for those who want to use the latest Flash updates. I use Chromium. Is there any way to get Chromium use the Flash from Google Chrome? The reason I as this question is that I have noticed both these browsers run in the background, so technically, the browsers' plugins are available to use. What kind of things can you take from a hotel? Hotels normally provide a big amount of sets (well, depending on the quality, but however, many!) that can help you feel more comfortable there.  So for example you can get towels, slippers, candies, pens, shampoos, shaving kits, sponges, ...  The same in the self-service breakfast: pastries, bread, ...  They are meant to be used during your stay. However, they can be provided in such an amount that there are some extra by the time you leave... and make you feel like taking some back home.  My general rule is to take those things that I used but didn't finish. However, sometimes I may be tempted to take the brand new stuff lying there before I close the door for the last time.  So the question that pops is: what kind of things is it correct to take from hotels and what is it not recommended? Else, what items may differ from country to country?

How do I pipe each command given to the shell? I'd like to edit my .bashrc so that every command executed on the shell is piped to something, for example:   $ sudo apt update   _________________ &lt; sudo apt update &gt;  -----------------     \   ^__^      \  (oo)\_______         (__)\       )\/\             ||----w |             ||     ||   I have managed something rather similar, but not entirely:  $ bash $ exec &gt; &gt;(cowsay) $ echo "Hello AU!" $ exit  _______ &lt; Hello AU! &gt;  -------     \   ^__^      \  (oo)\_______         (__)\       )\/\             ||----w |             ||     ||   It is not the desired result, as it only happens after exiting the current shell.

On @Shadow Wizard 's advice I've taken a screen shot of the 'error' notification (I had to scroll down to get all 10 'errors' on screen, hence the need for separate screen-shots) I have a set of Photoshop files which consist of a base image with a series of layers with colored overlays. The overlays are labeled using the layer names.  My task is to get these overlays as SVG paths, somehow preserving the labels. (If I can preserve the fill colors as well, that would be cool, but we can define arbitrary fill colors if needed.)  So far we have tried exporting the layers as Illustrator paths, and then exporting to SVG from Illustrator. This gets us reasonable SVG paths, but (a) we lose the labels, and (b) if a layer has more than one discrete section in its overlay, it is separated into several paths.  Is there a way to get these layers into SVG while retaining the labels? Or should we do our Export > Illustrator > SVG  route on a layer-by-layer basis?  We're working with CS5, if that's important.  ETA to answerers: We've long since finished this project and delivered the job, so I can't accept an answer, but feel free to pitch in your potential solutions for others.
