I already have some code to generate 2D kml files, but I am interested in reproducing an image similar to this, with an associated depth profile to each position:
Is there a good reference (or perhaps python library) for doing this? I have not managed to find anything.
Image reference:
Baird, R.W., S.W. Martin, D.L. Webster, and B.L. Southall. 2014. Assessment of Modeled Received Sound Pressure Levels and Movements of Satellite-Tagged Odontocetes Exposed to Mid-Frequency Active Sonar at the Pacific Missile Range Facility: February 2011 Through February 2013. Prepared for U.S. Pacific Fleet, submitted to NAVFAC PAC by HDR Environmental, Operations and Construction, Inc.
You may use other language to generate some kml files like the one in the following link:
https://sites.google.com/site/canadadennischen888/home/kml/3d-tracking
click download the attached file
select "save as" to see the KML content
select "open" to see result in Google Earth
hope this help
If you are using java, I have code to generate kml to display 3D tracking in google earth. (plus, a vertical line from air to ground for each point).
(assumption: Since you had code for 2D, you may already have java pojo code that converted from kml21.xsd.)
(p.s. I can attached you an image if you know any free site for me to upload image.)
Hope this help:

Hi there, I'm trying to import the CtCI library to solve the problem but there's an error message. And from her GitHub, that was how she imported this class. I know we can import the class from java built-in library. But I'm not sure how import works when trying to import from someone else. Could someone explain it to me?
If you are doing serious programming for a long term app, and by import you refer to libraries/dependencies, I highly recommend you using maven for it.
If you don't use maven yet, you can just add the .jar files from you IDE to your project path, but with maven is way better.
If you mean importing a .java file written by someone else, to use part of it in your code, just put the file at your project path, you probably need to adapt its libraries and imports, and once ready you can just use its methods ans stuff. Just make sure you have tipped at the top of your current file the import sentence of that file.
The question Leaflet plugin only working when geolocation is enabled had a nice wrapping of the OverpassLayer OSM for react-leaflet. Unfortunately, it only works for react-leaflet v1.
import { LayerGroup } from "react-leaflet";
import L from "leaflet";
import OverPassLayer from "leaflet-overpass-layer";
export default class OverpassLayer extends LayerGroup {
componentWillReceiveProps(nextProps) {
console.log(nextProps.key);
console.log("OverpassLayer receiving props");
const query = "("
+ "node[\"amenity\"]({{bbox}});"
+ "way[\"amenity\"]({{bbox}});"
+ "relation[\"amenity\"]({{bbox}});"
+ ");"
+ "out body;"
+ ">;"
+ "out skel qt;";
const opl = new L.OverPassLayer({
"query": query,
"endPoint": "https://overpass-api.de/api/",
});
nextProps.map.addLayer(opl);
}
}
With v2, it doesn't work, ending with the error:
TypeError: Super expression must either be null or a function
Any idea on how to update this code to v2?
As for everything in react-leaflet v2, we need to reimplement the intermediate class (LayerGroup) as well:
// #flow
import LeafletOverPassLayer from "leaflet-overpass-layer";
import { withLeaflet, MapLayer } from "react-leaflet";
import type { MapLayerProps } from "react-leaflet";
type LeafletElement = LeafletOverPassLayer;
type Props = MapLayerProps;
class OverPassLayer extends MapLayer<LeafletElement, Props> {
createLeafletElement(props: Props): LeafletElement {
const el = new LeafletOverPassLayer({
query: "("
+ "node[\"amenity\"]({{bbox}});"
+ "way[\"amenity\"]({{bbox}});"
+ "relation[\"amenity\"]({{bbox}});"
+ ");"
+ "out body;"
+ ">;"
+ "out skel qt;",
endpoint: "https://overpass-api.de/api/",
minZoomIndicatorEnabled: false,
}, this.getOptions(props));
this.contextValue = { ...props.leaflet, layerContainer: el };
return el;
}
}
export default withLeaflet<Props, OverPassLayer>(OverPassLayer);
It's basically copy/paste + adding the overpass information. Here we display all amenities as a red circle.
Removed the zoom indicator as it seems to be missing an onRemove method.
V2 of react-leaflet completely breaks the ability to extend many components. I raised an issue about this a while ago:
https://github.com/PaulLeCam/react-leaflet/issues/506
This is an intentional design choice by the library's author (a choice that I wholeheartedly disagree with but that's a moot point)
Read through that Github thread and if you have further questions just ask :)
I'd like to to export AEM reports, page activity or component activity reports, in an excel file.
Is this feature is available in AEM or do I have to write custom for this?
The closest you will get is a CSV selector that can convert report data to CSV but even that has limitations (pagination, filters may be ignored depending on the report).
This, AFAIK, is not an OOTB function. There are old posts and blogs out there to show how this can be done on bpth client side (using JS) or server side using CSV writers.
If you are going down the route of writing a custom solution (most likely outcoume), have a look at the CSV text library that is used in acs-commons user CSV import/export utility, that makes the job really easy and is already a part of AEM.
Hope this helps.
The WriteExcel class simply takes the List collection that is used to populate the JTable object and writes the data to an Excel spreadsheet.
This class uses the Java Excel API. The Java Excel API dependency that is required to work with this API is already in the POM dependencies section.

You can follow the steps described here: Adobe Forums
Select your required page to see component report at http://localhost:4502/etc/reports/compreport.html
Now hit the below URL. It gives you JSON output. http://localhost:4502/etc/reports/compreport/jcr:content/report.data.json
Copy paste the generated JSON output at below URL and click on JSON to excel http://www.convertcsv.com/json-to-csv.htm
You need to write your own logic
create a servlet,
construct Table with data
in the response object add below lines
response.setContentType("text/csv");
response.setCharacterEncoding("UTF-8");
response.setHeader("Content-Disposition", "attachment; filename=\"" + reportName + ".csv\"");
Cookie cookie = new Cookie("fileDownload", "true");
cookie.setMaxAge(-1);
cookie.setPath("/");
response.addCookie(cookie);
once click on the button you will get the report in the Excel format.
I am trying to recreate a tax map within my system using Bing Maps. My problem is in listing the length, in feet, of the sides of the polygons I am creating. I have a good idea of how to get the length of polylines I am creating from the MSSQL 2012 geometry or geography items in my database. I cannot figure out how to present it to the user effectively though. I have two ideas for how I would like to do this.
Place the lengths directly on or adjacent to the polyline in question.
Create an emphasized point on the full polygon and list to the side of the map, the lengths of the sides of the polygon based on a clockwise order.
Either of the 2 options would work as an acceptable solution. I used this tutorial to create my current environment so I would be looking to integrate the solution into it in some way:
How to create a spatial web service that connects a database to Bing Maps using EF5
Note that my implementation only uses the countries part of the code so I do not need to deal with single points like cities that are in that tutorial.
The relevant piece of code that handles drawing on the map that I would need to edit can be found here:
Bing Maps v7 WellKnowTextModule
If you want to get the perimeter of a polygon in SQL2012 you can grab the exterior ring of it. The exterior ring will be a LineString i.e. "#g.STExteriorRing()". Then measure the length along that line. i.e. "#g.STExteriorRing().STLength()". However, countries are usually not just single Polygons, they can be MultiPpolygons, or GeometryCollections. So to calculate these lengths we have to do a bit more work. Here is a helper method you can add to the service to calculate the perimeters of these shapes:
private double CalculateLength(SqlGeometry geom)
{
double length = 0;
if(string.Compare(geom.STGeometryType().Value, "polygon", true) == 0)
{
}
else if (string.Compare(geom.STGeometryType().Value, "multipolygon", true) == 0)
{
int numPolygon = geom.STNumGeometries().Value;
for(int i = 1; i <= numPolygon; i++){
length += geom.STGeometryN(i).STExteriorRing().STLength().Value;
}
}
else if (string.Compare(geom.STGeometryType().Value, "geometrycollection", true) == 0)
{
int numGeom = geom.STNumGeometries().Value;
for (int i = 1; i <= numGeom; i++)
{
length += CalculateLength(geom.STGeometryN(i));
}
}
return length;
}
To get the length info from the server side to the client add a property to the Country or BaseEntity class like this:
[DataMember]
public double Perimeter { get; set; }
From here you can populate this value after the linq query is used to get the response results using a simple loop that calls the helper method from earlier:
for (int i = 0; i < r.Results.Count;i++)
{
var geom = SqlGeometry.STGeomFromText(new System.Data.SqlTypes.SqlChars(r.Results[i].WKT), 4326);
r.Results[i].Perimeter = CalculateLength(geom);
}
As for displaying the information on the map. An easy way to place the information on a polyline is to choose a coordinate along the line, perhaps the middle one, just get the # or coordinates in the line and find the middle index and use that coordinate for a pushpin. You can then create a custom push using either a background image with text, or using custom HTML:
http://www.bingmapsportal.com/ISDK/AjaxV7#Pushpins4
http://www.bingmapsportal.com/ISDK/AjaxV7#Pushpins15
Wanted to add an addendum to the answer I accepted as I feel it changes it a bit.
While working on this I found that I was not actually able to get each line segment's length via entity framework. This is due to the fact that the query required changing the geography I had back to a geometry then parse it to its base line segments and then change those line segments back to geographies. The query, even in SQL, would take minutes so it was not an option to run dynamically in EF.
I ended up creating another table in my database containing the parsed line segments for each side of each polygon I had. Then I could use the centroids of the line segments as faux cities. I then added this logic into the DisplayData javascript function from the tutorial mentioned in the question after the for loop in the method.
if (shape.getLength) {
} else {
var chkPolygon = data.Results[0].WKT.substring(0, data.Results[0].WKT.indexOf('(', 0));
chkPolygon = chkPolygon.replace(/\s/g, '');
switch (chkPolygon.toLowerCase()) {
case 'point':
case 'polygon':
var latlonCheck = map.getCenter();
var setSides = window.location.origin + "/SpatialService.svc/FindNearBy?latitude=" +
latlonCheck.latitude + "&longitude=" + latlonCheck.longitude +
"&radius=" + data.Results[0].ID + "&layerName=" + "city" + "&callback=?";
CallRESTService(setSides, DisplaySides);
default:
break;
}
}
the data.Results[0].ID would find all the line segments in the new table for that specific country. Then the DisplaySides function is used to overlay the html pushpins as "cities" over the appropriate points for each side on the map
function DisplaySides(getSides) {
infobox.setOptions({ visible: false });
if (getSides && getSides.Results != null) {
for (var i = 0; i < getSides.Results.length; i++) {
var sideLenFtShort = Math.round(getSides.Results[i].LengthFeet * 100) / 100;
var htmlLenString = "<div style='font-size:14px;border:thin solid black;background-color:white;font-weight:bold;color:black;'>" + sideLenFtShort.toString(); + "</div>";
var testString = {
pushpinOptions: { width: null, height: null, htmlContent: htmlLenString }
};
var sideCtr = WKTModule.Read(getSides.Results[i].WKT, testString);
dataLayer.push(sideCtr);
}
}
else if (getSides && getSides.Error != null) {
alert("Error: " + getSides.Error);
}
}
I'm trying to dynamically create a PowerPoint presentation. One slide has a bunch of placeholder images that need to be changed based on certain values.
My approach is to create a new ImagePart and link it to the according Blip. The image is downloaded and stored to the presentation just fine. The problem is, that there is no relationship created in slide.xml.rels file for the image, which leads to an warning about missing images and empty boxes on the slide.
Any ideas what I am doing wrong?
Thanks in advance for your help! Best wishes

So, for everyone who's experiencing a similar problem, I finally found the solution. Quite a stupid mistake. Instad of PresentationDocument document = PresentationDocument.Open(mstream, true); you have to use
using (PresentationDocument document = PresentationDocument.Open(mstream, true))

This answer brought me on the right way.
