Spatial datasets operations: When the sky is failing

Not all raster can be re-projected to another projection, at least some tools don't allow us to.

For example, the AMSR-E/Aqua L3 Global Snow Water Equivalent EASE-Grids cannot be directly re-projected to UTM-6N within ENVI 5.1.
https://nsidc.org/data/docs/daac/ae_swe_ease-grids.gd.html
Please refer this website for projection information.

 Fortunately, ArcMap can do a better job in this scenario.
You can use the project tool just like any other operations.

In order to re-project lot of data using ArcObject, I have updated a ArcTool, which is basically a batch mode data operation toolkit. For this task, the screenshot is as follow:



Below is the result:





Beneath the hook is the GP tool, some sample scripts are as follow:
///================================================
public static object ProjectRaster(string sFileIn, string sFileOut, string sNewProject, double dCellSize)
        {
            ESRI.ArcGIS.Geoprocessor.Geoprocessor gp = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            ///========================================
            ///disable the pyramid 
            ///========================================
            gp.ResetEnvironments();      
            gp.SetEnvironmentValue("Pyramid", "NONE");          
            gp.OverwriteOutput = true;
            ///=================================
            ProjectRaster pProjectRaster = new ProjectRaster(sFileIn, sFileOut, sNewProject);
            pProjectRaster.cell_size = dCellSize;
            ///pProjectRaster.resampling_type = "BILINEAR";
            pProjectRaster.resampling_type = "NEAREST";
            return gp.Execute(pProjectRaster, null);
        }
///=================================================

Remember that sometimes the environment setting can be messy, so you can always setup them explicitly following (even though the ESRI document itself is a mess):



One may ask, why would you re-project such a raster to the other projection which is not supported in ENVI?
There are other methods, maybe better ones to achieve this task. And this is just a demonstration of how to make use of the GP tool in ArcObject when ENVI/IDL fails.

Spatial datasets operations: mask raster using region of interest

Climate change related studies usually involve spatial datasets extraction from a larger domain.
In this article, I will briefly discuss some potential issues and solutions.

In the most common scenario, we need to extract a raster file using a polygon based shapefile. And I will focus as an example.

In a typical desktop application such as ArcMap or ENVI, this is usually done with a tool called clip or extract using mask or ROI.

Before any analysis can be done, it is the best practice to project all datasets into the same projection.

If you are lucky enough, you may find that the polygon you will use actually matches up with the raster grid perfectly. But it rarely happens unless you created the shapefile using "fishnet" or other approaches.

What if luck is not with you? The algorithm within these tool usually will make the best estimate of the value based on the location. The nearest re-sample, but not limited to, will be used to calculate the value. But what about the outp…

Numerical simulation: ode/pde solver and spin-up

For Earth Science model development, I inevitably have to deal with ODE and PDE equations. I also have come across some discussion related to this topic, i.e.,

https://www.researchgate.net/post/What_does_one_mean_by_Model_Spin_Up_Time

In an attempt to answer this question, as well as redefine the problem I am dealing with, I decided to organize some materials to illustrate our current state on this topic.

Models are essentially equations. In Earth Science, these equations are usually ODE or PDE. So I want to discuss this from a mathematical perspective.

Ideally, we want to solve these ODE/PDE with initial condition (IC) and boundary condition (BC) using various numerical methods.

Because of the nature of geology, everything is similar to its neighbors. So we can construct a system of equations which may have multiple equation for each single grid cell. Now we have an array of equation…

Lessons I have learnt during E3SM development

I have been involved with the E3SM development since I joined PNNL as a postdoc. Over the course of time, I have learnt a lot from the E3SM model. I also found many issues within the model, which reflects lots of similar struggles in the lifespan of software engineering.

Here I list a few major ones that we all dislike but they are around in almost every project we have worked on.

Excessive usage of existing framework even it is not meant to Working in a large project means that you should NOT re-invent the wheels if they are already there. But more often, developers tend to use existing data types and functions even when they were not designed to do so. The reason is simple: it is easier to use existing ones than to create new ones. For example, in E3SM, there was not a data type to transfer data between river and land. Instead, developers use the data type designed for atmosphere and land to do the job. While it is ok to do so, it added unnecessary confusion for future development a…
