, advantages: simple operation, just enter the simple first letter can complete the command, with the mouse movement automatically display relevant information, you can enter the operation instructions at any time. Disadvantage: CAD is sometimes too cumbersome to operateCass Software is a software system based on CAD platform developed by Guangdong Southern Digital Technology Co., Ltd, which integrates terrain, cadastral, spatial data building, engineering application, earthwork calculation and
next 12 months, the ArcGIS Web and Runtime SDKs will fully support the use of device applications built on the Runtime and Web, leveraging the benefits of 3D workflows and information products.At the end of this year, we will also release a new client application ArcGIS earth--an easy-to-use desktop application that supports KML workflows and integrates with the ArcGIS platform. Vector slicing, which previously described support for 2D, is also supported in Web and mobile applications. For more

, you can add some nautical themes for the screen to add color. The use of sea-view is also very extensive, such as wedding dress, can be two new kiss the seabed, the screen is extremely beautiful and attractive, can also be SNS, pull down the scrolling mode to make the page meaningful, or seafood mall, these are very good design. No matter what kind of way, can let the picture has a very strong impact, and even the product and the sea Fu
select a suitable unit. Not all units can be adjusted, for example: fan speed. Depending on some user feedback, the system may not be able to automatically control fan speed after using this feature. Workaround: Time Machine Restore the backup or reload the system. Low power prompts are required for each operating system, but will only be shown when the power trigger warning, as a third-party application of the IStat Menus can compensate for this aspect of the "defect"
useful distance calculation function, using latitude and longitude to calculate the distance from A location to B location. The function can return miles, kilometers, nautical kilometres of three units of distance. Copy Code code as follows: function distance ($lat 1, $lon 1, $lat 2, $lon 2, $unit) { $theta = $lon 1-$lon 2; $dist = sin (Deg2rad ($lat 1)) * Sin (Deg2rad ($lat 2)) + cos (Deg2rad ($lat 1)) * cos (Deg2rad ($lat 2)) *

Literally, blog is the abbreviation of weblog, weblog is "Web" and "Log" combination, log Chinese meaning is "nau
Also known as the positive axis conformal cylindrical projection. A cylindrical projection of a kind, by the Dutch map biologist Mercator (G. Mercator) was created in 1569. Is the most influential in the map projection method.Imagine a cylinder aligned with the axis of the Earth cut or cut in the world, according to the isometric conditions of the graticule projection to the cylindrical surface, the cylindrical surface to show as a plane, the plane longitude net. The post-projection meridian is
document and add the keyword as a string to the array. You can then create a multi-key index on this array and create a query to select values from this array. Instance: Given a collection of book volumes and want to provide a search for an opportunity topic. For each volume, we increase the topics array and add the keyword to the array as much as possible for the volume. The Moby-dick volume can be represented by the following document. {title: "Moby-dick" , "Herman Melville" , 1851 , 0
