I want to create a elevation profile of a cross section so a polyline on ArcGIS. I wanted to regularly space around 1000 points per 1700m long xsection and extract elevation data for each node/point from the underlying LiDAR raster to create a graph showing elevation vs distance. However, at the moment I am having to use the intersect function with my 0.2m interval contours, which is ok but then it only extracts an elevation where the contour intersects the cross section. So is it possible to create these regularly spaced nodes/points along the xsection, if so how do I do it?
Assuming that you have your xsection marked as polyline. It may be way around but try to use free ET Geowizzard/Polyline/Densify tool, which allows to create/add nodes (on the existing polyline) in 3 ways (have a look). Next, use ET Geowizard/Convert/Polyline to Point or PolylineMZ to Point (extract nodes to points). Next use Sample tool from Spatial Analyst (if available) to derive Z vale from raster to point. At this stage by point I mean table with coords X, Y, Raster_Value. If this is not enough, from this table in the ArcCatalog right click on the table and use Crate Feature ClassExport XY. This will creat Point M(Z).
Creating an API key
To use any LDS web service or API, you will first need to create an API key.
LDS web services start with a key
Your key is a long string of characters unique to your LDS account and allows you to access your LDS account without you having to provide your password.
Only registered users of the LINZ Data Service can create API keys, and all web services providing data require an API key.
Once you have created your key, if you are logged into LDS and select a web service URL, your web service key is automatically populated in the URL for you to easily copy and paste into your application.
Here is an example of an LDS WMTS Get Capabilities URL that has a web services key included:
How to create a LDS API key
- Login to LDS and click on your name in the top menu, then click APIs & Web Services to go to the following page:
- Use the Label field to give your API key a name
- Select ‘Data access only’
- Accept terms and create key
Find more information about API keys and the services they provides access to at the Koordinates Support site.

They make precise measurements to determine property boundaries. They provide data relevant to the shape and contour of the Earth's surface for engineering, mapmaking, and construction projects.
Set the "Restrict where this job can be run" check box in your job configuration and specify the name of your slave.
If you add more slaves later, you can set labels for each slave and specify those in your job configs.
See this reference documentation:
If you are running a Pipeline job, you first want to add a label (e.g. 'slave') to the slave node (or agent as it seems to be called now).
Then, in the pipeline script, you specify the label the job runs on:
This job will now run on any node with the label 'slave'. If you only want the job to run on this particular slave, don't reuse the label. And of course the label doesn't have to be 'slave' it can be whatever you want.
In the scripted pipeline, if your node is named "My Node", you can also do this:
If you only want the code block to run on that particular node, this is useful. However, using labels is more flexible, and can make it easier to add nodes to share the workload.
How Many Cells Are In Your Body?
A simple question deserves a simple answer. How many cells are in your body? Unfortunately, your cells can't fill out census forms, so they can't tell you themselves.
A simple question deserves a simple answer. How many cells are in your body?
Unfortunately, your cells can’t fill out census forms, so they can’t tell you themselves. And while it’s easy enough to look through a microscope and count off certain types of cells, this method isn’t practical either. Some types of cells are easy to spot, while others–such as tangled neurons–weave themselves up into obscurity. Even if you could count ten cells each second, it would take you tens of thousands of years to finish counting. Plus, there would be certain logistical problems you’d encounter along the way to counting all the cells in your body–for example, chopping your own body up into tiny patches for microscopic viewing.
For now, the best we can hope for is a study published recenty in Annals of Human Biology, entitled, with admirable clarity, “An Estimation of the Number of Cells in the Human Body.”
The authors–a team of scientists from Italy, Greece, and Spain–admit that they’re hardly the first people to tackle this question. They looked back over scientific journals and books from the past couple centuries and found many estimates. But those estimates sprawled over a huge range, from 5 billion to 200 million trillion cells. And practically none of scientists who offered those numbers provided an explanation for how they came up with them. Clearly, this is a subject ripe for research.
If scientists can’t count all the cells in a human body, how can they estimate it? The mean weight of a cell is 1 nanogram. For an adult man weighing 70 kilograms, simple arithmetic would lead us to conclude that that man has 70 trillion cells.
On the other hand, it’s also possible to do this calculation based on the volume of cells. The mean volume of a mammal cell is estimated to be 4 billionths of a cubic centimeter. (To get a sense of that size, check out The Scale of the Universe.) Based on an adult man’s typical volume, you might conclude that the human body contains 15 trillion cells.
So if you pick volume or weight, you get drastically different numbers. Making matters worse, our bodies are not packed with cells in a uniform way, like a jar full of jellybeans. Cells come in different sizes, and they grow in different densities. Look at a beaker of blood, for example, and you’ll find that the red blood cells are packed tight. If you used their density to estimate the cells in a human body, you’d come to a staggering 724 trillion cells. Skin cells, on the other hand, are so sparse that they’d give you a paltry estimate of 35 billion cells.
So the author of the new paper set out to estimate the number of cells in the body the hard way, breaking it down by organs and cell types. (They didn’t try counting up all the microbes that also call our body home, sticking only to human cells.) They’ve scoured the scientific literature for details on the volume and density of cells in gallbladders, knee joints, intestines, bone marrow, and many other tissues. They then came up with estimates for the total number of each kind of cell. They estimate, for example, that we have 50 billion fat cells and 2 billion heart muscle cells.
Adding up all their numbers, the scientists came up with … drumroll … 37.2 trillion cells.
This is not a final number, but it’s a very good start. While it’s true that people may vary in size–and thus vary in their number of cells–adult humans don’t vary by orders of magnitude except in the movies. The scientists declare with great confidence that the common estimate of a trillion cells in the human body is wrong. But they see their estimate as an opportunity for a collaboration–perhaps through an online database assembled by many experts on many different body parts–to zero in on a better estimate.
Curiosity is justification enough to ponder how many cells the human body contains, but there can also be scientific benefits to pinning down the number too. Scientists are learning about the human body by building sophisticated computer models of lungs and hearts and other organs. If these models have ten times too many cells as real organs do, their results may veer wildly off the mark.
The number of cells in an organ also has bearing on some medical conditions. The authors of the new study find that a healthy liver has 240 billion cells in it, for example, but some studies on cirrhosis have found the disease organ have as few as 172 billion.
Perhaps most importantly, the very fact that some 34 trillion cells can cooperate for decades, giving rise to a single human body instead of a chaotic war of selfish microbes, is amazing. The evolution of even a basic level of multicellularity is remarkable enough. But our ancestors went way beyond a simple sponge-like anatomy, evolving a vast collective made of many different types. To understand that collective on a deep level, we need to know how big it really is.

When fleas infected with the bacterium Yersinia pestis bite humans, the bacteria can jump into the bloodstream and congregate in humans’ lymph nodes, which are found throughout the body. The infection causes lymph nodes to swell into ghastly “buboes,” the namesakes for bubonic plague. (Find out how plague bacteria evolved.)
In cases of plague since the late 1800s—including an outbreak in Madagascar in 2017—rats and other rodents helped spread the disease. If Y. pestis infects rats, the bacterium can pass to fleas that drink the rodents’ blood. When a plague-stricken rat dies, its parasites abandon the corpse and may go on to bite humans.
Because of rats’ role in modern plagues, as well as genetic evidence that medieval plague victims died of Y. pestis, many experts think that rats also spread plague during the Second Pandemic.
But some historians argue that the Black Death may have spread differently. For one, the Black Death tore through Europe far faster than any modern plague outbreaks. In addition, “rat falls” precede some modern outbreaks, but medieval plague records don’t mention rats dying en masse.
“Geneticists and modern historians were putting the rat into the position [of spreading the plague] and were straining bits of evidence,” says Samuel Cohn, a University of Glasgow medieval historian who has criticized the rat-flea theory.
Stages of plague
For hundreds of years, what caused plague outbreaks remained mysterious, and shrouded in superstitions. But keen observations and advances in microscopes eventually helped unveil the true culprit. In 1894, Alexandre Yersin discovered the bacterium responsible for causing plague: Yersinia pestis.
Y. pestis is an extraordinarily virulent, rod-shaped bacterium. Y. pestis disables the immune system of its host by injecting toxins into defense cells, such as macrophages, that are tasked with detecting bacterial infections. Once these cells are knocked out, the bacteria can multiply unhindered.
Many small mammals act as hosts to the bacteria, including rats, mice, chipmunks, prairie dogs, rabbits, and squirrels. During an enzootic cycle, Y. pestis can circulate at low rates within populations of rodents, mostly undetected because it doesn’t produce an outbreak. When the bacteria pass to other species, during an epizootic cycle, humans face a greater risk for becoming infected with plague bacteria.
Rats have long been thought to be the main vector of plague outbreaks, because of their intimate connection with humans in urban areas. Scientists have more recently discovered that a flea that lives on rats, Xenopsylla cheopis, primarily causes human cases of plague. When rodents die from the plague, fleas jump to a new host, biting them and transmitting Y. pestis. Transmission also occurs by handling tissue or blood from a plague-infected animal, or inhalation of infected droplets.
Bubonic plague, the disease's most common form, refers to telltale buboes—painfully swollen lymph nodes—that appear around the groin, armpit, or neck. The skin sores become black, leading to its nickname during pandemics as “Black Death.” Initial symptoms of this early stage include vomiting, nausea, and fever.
Pneumonic plague, the most infectious type, is an advanced stage of plague that moves into the lungs. During this stage, the disease is passed directly, person to person, through airborne particles coughed from an infected person’s lungs.
If untreated, bubonic and pneumonic plague can progress to septicemic plague, infecting the bloodstream. If left untreated, pneumonic and septicemic plague kills almost 100 percent of those it infects.

From segments to individuals
We’ve talked about the importance of Big Data to investigate changes in sentiment and to identify specific target segments to interface with. But can you go beyond that? Yes.
And what’s beyond segments? Individuals, with their unique characteristics, behaviors, and specific needs. Big Automotive brands, but also dealers, can now move from one-to-many marketing to the one-to-one revolution .
Personalization is one of the oldest and most effective business strategies. Today it takes on new life thanks to the most powerful technologies made available by Digital Transformation. And personalization is what companies like Doxee do , providing solutions that can be invaluable in the automotive presale phase.
- : Represents a revolution in the way that data, offers, and complex information are communicated to customers. It’s about creating real dynamic and interactive microsites built based on the characteristics, behaviors, and needs of each individual . , a tool that combines the effectiveness of video communication with the boost of personalization .
Think of the possibilities of being able to “see,” in detail, the car you are thinking about buying through a video that is created based on your characteristics. Think about how valuable this tool can be in the various presale phases (above all, for the estimate), but also in the post-sale phases (service, maintenance and Customer Care in general).
The big automotive brands have realized that personalization can be the key to winning the challenges of the future (there are interesting examples from BMW , see here, and from Mercedes , see here).
They have realized, in short, that the digital revolution is the turning point to look to the future after this period of crisis. It’s a revolution that has the individual driver at its center.
