Introduction to  spatial queries  in SQL Server 2012
 
30:01
The amount of spatial data captured in databases is increasing exponentially. This includes data from mobile phones, GPS units through to home detention bracelets. Typically these devices capture location information in the form of latitudes and longitudes. The spatial capabilities of SQL Server has been significantly enhanced with the release of Microsoft SQL Server 2012. SQL now has some of the best spatial functionality of all the mainstream databases. Spatial queries use different syntax to the T-SQL that traditional queries use. This tutorial will provide an introduction to creating spatial queries that perform tasks such as - Viewing shapes within SQL Server. - Calculating the length of direct and indirect routes. - Area of shapes such as polygons or buffered points - Whether coordinates fall within a a predefined area such as a polygon, circle or buffered line string. Demonstration files are available from my website (link provided in video). I also have a comprehensive 60 minute T-SQL course available at Udemy : https://www.udemy.com/t-sql-for-data-analysts/?couponCode=ANALYTICS50%25OFF

MongoDB - Back to Basics 4 - Advanced Indexing, Text and Geo-spatial Indexes
 
43:22
In this fourth webinar of our back to basics series Joe Drumgoole, Director of Developer Advocacy EMEA at MongoDB, looked into the full-text index support and geospatial support available in MongoDB. - Full text support allows a user to index all the textual content in their database allowing “google like” searches over the data set. - Geospatial indexes allow a user to store geospatial coordinates in the data and do searches based on the proximity of one point to another. This is a fundamental requirement for many mobile applications.

LASindex - simple spatial indexing of LiDAR data
 
33:12
Airborne LiDAR surveys collect large amounts of elevations samples, often resulting in Terabytes of data. The acquired LiDAR points are typically stored and distributed in the LAS format or - its lossless compressed twin - the LAZ format. However, managing a folder of LAS or LAZ files is not a trivial task when a survey consists, for example, of 500 flight strips containing around 200 million points each. Even a simple area-of-interest (AOI) query requires opening all files and loading all those whose bounding box overlaps the queried AOI. One solution is to copy the survey into a dedicated data base such as Oracle Spatial or PostgreSQL. We present a much simpler alternative that works directly on the original LAS or LAZ files. To facilitate the exchange of data between users and across software packages, the ASPRS created the LAS format that is now the accepted industry standard for airborne LiDAR. To lower the storage requirements and reduce the transmission bandwidth for LAS files, we proposed the LAZ format - a lossless compressed twin of the LAS format - that is gaining traction in the industry as more and more data providers offer LAZ files (e.g. NOAA, National Land Survey of Finland, Open Topography, USGS, Dielmo3D, DNR Minnesota, ...) and more and more software has LAZ support (e.g. Global Mapper, TopoDOT, FME 2012, QT Modeler, RiProcess, Fugroviewer, ...). However, the total size of all LAS or LAZ files from one survey still poses a significant challenge as billions of elevation samples need to be managed for processing and distribution. This problem is getting more pronounced as the resolution and converage of LiDAR surveys continues to increase. A common solution is to create a second copy of the entire survey by loading it into a dedicated spatial data base such as Oracle Spatial or PostgreSQL. Once all the data was uploaded it can then be efficiently queried using established data base technology. But this approach has high start-up costs in terms of time, money, and disk space: the acquisition and installation time for a large software package, possible licensing delays and costs, the time needed to copy the entire survey into the database, and finally the additional disk space required for this second copy. While this initial investment may pay off over time, we describe a much simpler alternative that provides a different trade-off by working directly in-place on the original LAS or LAZ files. Our minimal-effort spatial indexing scheme has very small setup costs, avoids creating a second copy of the data, and is already in use in the LAStools software suite (see Figure~\ref{fig:gui}). For each LiDAR file we generate a tiny LAX file that resides in the same folder as the *.las or *.laz file and has the same name but with a *.lax extension. The LAX files are generally as small as 0.01 percent (for a LAS file) or 0.1 percent (for a LAZ file) of the file containing the LiDAR data and they can be generated as fast as the points can be read off disk. The LAX files describe an adaptive quadtree over the x and y coordinates of all points. Each occupied quadtree cell stores a list of point index intervals that together reference all points falling into this cell. By merging all intervals of a cell that are less than 1000 apart in point index space we significanly reduce the number of intervals, the size of the LAX files, and the number of file seek operations. Although individual cells typically reference too many points this is usually amortized as a typical AOI query will require returning a union of all intervals from many quadtree cells. However, our in-place spatial indexing relies on a certain degree of spatial coherency to be present in the point order. A simple measure of the efficiency of the existing order is to calculate the overhead factor when loading each quadtree cell individually from disk. The source code for LASindex is freely available under a LGPL license within the open source libraries LASlib of LAStools. It has been extensively field-tested in the LiDAR delivery pipeline of Open Topography (OT) where it is used to efficiently gather data from folders of LAZ files in accordance to area-of-interest queries that are generated by users via OT's popular web-based LiDAR download interface. Another important use is on-the-fly point buffering. When batch processing, for example, 2km by 2km LiDAR tiles to create DTMs via rasterization of a temporary TIN, it is beneficial to load a 100 meter point buffer around each tile to avoid tile boundary artifacts. The presence of LAX files allows doing so efficiently on-the-fly.

Hierarchy ID is nothing other then column which represent relational value in numeric format on which DFS (Depth First Search) & BFS (Breadth First Search) can be used The concept is very simple, when we have to make relational structures which shows parent child level tree hierarchy, we can use hierarchyid datatype. With hierarchy ID recursive queries can be converted into range query. DFS (Depth First Search) and BFS (Breadth First Search) can be implemented using additional index which improves performance. Uses .NET assembly library defined methods to provide easy maintenance. Hierarchy ID is scalar column and is sequence of no. of var binary values.

mysql tutorial for beginners (6/8) : Indexes
 
05:48
mysql tutorial for beginners (6/8) : Indexes As things stand, the table students works and can be searched without problem by MySQL—until it grows to more than a couple of hundred rows, At that point, database accesses will get slower and slower with every new row added, because MySQL has to search through every row whenever a query is issued. This is like searching through every book in a library whenever you need to look something up. Of course, you don’t have to search libraries that way, because they have either a card index system or, most likely, a database of their own. The way to achieve fast searches is to add an index, either when creating a table or at any time afterward. But the decision is not so simple. For example, there are different index types such as a regular INDEX, PRIMARY KEY, and FULLTEXT. Also, you must decide which columns require an index, a judgment that requires you to predict whether you will be searching any of the data in that column. And even when you’ve decided that, you still have the option of reducing index size by limiting the amount of each column to be indexed. If we imagine the searches that may be made on the students table, it becomes apparent that all of the columns may need to be searched. Anyway, go ahead and add an index to each of the columns, using the commands: ALTER TABLE students ADD INDEX(name(3)); An alternative to using ALTER TABLE to add an index is to use the CREATE INDEX command. They are equivalent, except that CREATE INDEX cannot be used for creating a PRIMARY KEY CREATE INDEX surname ON students (surname(5)); DESCRIBE students; These commands create indexes on both the name and surname columns, limiting name index to only the first 3 characters, and surname index to the first 5 characters. For instance, when MySQL indexes the following name: SAFAA It will actually store in the index only the first 3 characters: SAF This is done to minimize the size of the index, and to optimize database access speed. DESCRIBE command shows the key MUL for each column. This key means that multiple occurrences of a value may occur within that column, which is exactly what we want, as name or surname may appear many times. You don’t have to wait, until after creating a table to add indexes. In fact, doing so can be time-consuming, as adding an index to a large table can take a very long time. Therefore, let’s look at a command that creates the table students with indexes already in place. CREATE TABLE students ( Id_studnet SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(10) NOT NULL, surname VARCHAR(20) NOT NULL, email VARCHAR(30) NOT NULL, INDEX(name(3)), INDEX(surname(5)), ,PRIMARY KEY(id_studnet),UNIQUE(email)); Another important index, PK, its single unique key for each student to enable instant accessing of a row. The importance of having a key with a unique value for each row will come up when we start to combine data from different tables. You can add PK, while you create the table at the first time, or later by issuing the following command: ALTER TABLE students ADD PRIMARY KEY(id_student); The last important index, FULLTEXT index Unlike a regular index, MySQL’s FULLTEXT allows super-fast searches of entire columns of text. It stores every word in every data string in a special index that you can search using “natural language,” in a similar manner to using a search engine. It’s not strictly true that MySQL stores all the words in a FULLTEXT index, because it has a built-in list of more than 500 words that it chooses to ignore because they are so common that they aren’t very helpful for searching anyway. This list, called stopwords, includes the, as, is, of, and so on. The list helps MySQL run much more quickly when performing a FULLTEXT search and keeps database sizes down. FULLTEXT indexes can be created for CHAR, VARCHAR, and TEXT columns only. A FULLTEXT index definition can be given in the CREATE TABLE statement when a table is created, or added later using ALTER TABLE (or CREATE INDEX). Adding a FULLTEXT index to the table students for the columns name and surname ALTER TABLE classics ADD FULLTEXT(name,surname); this index is in addition to the ones already created and does not affect them You can now perform FULLTEXT searches across this pair of columns. If you find that MySQL is running slower than you think it should be when accessing your database, the problem is usually related to your indexes. Either you don’t have an index where you need one, or the indexes are not optimally designed. Tweaking a table’s indexes will often solve such a problem. In the next tutorial, we will learn about, using FOREIGN KEY Constraints and how to join tables together.

06:00
How to Compress an ArcSDE geodatabase? lets learn on how to compress an arcsde geodatabase launch arc catalog now point to note is that only an geodatabase administrator can compress the geodatabase so here we will use sde user to compress the gdb as of now we donot have any data in this db but still i can show you how to compress so we can either compress from here and it will be running in the background or we can run the compress tool. . COOL our database is compressed now now you notice that compress log is generated this compress log is generated in the beginning of the compress operation or when the compress operation is done first time on a database every time you compress the database, an entry of compress will be added in this compress log i will show you if the end_state_count is 1, that means the database is compressed to state 0. so it how we can compress its done For more information, write to us at www.arcsdesupport.com or visit arcsde.blogspot.in

MySQL 5.7: a GIS Reborn
 
40:10
by Matt Lord MySQL is reemerging within the spatial world in version 5.7 as we replace much of the old foundation by incorporating Boost.Geometry, by adding R-tree index support to the InnoDB engine, and by adding a number of helper functions (e.g. ST_Distance_Sphere). We've also begun paving the way for even more functionality moving forward, such as Projections and Geography. I will walk you through all of the new spatial features in MySQL 5.7, show some brief examples of how you can use them, and finally discuss where we'd like to go with future releases of MySQL.
