In this data rich world, we need to understand how things are organized on the Earth's surface. Those things are represented by spatial data and necessarily depend upon what surrounds them. Spatial statistics provide insights into explaining processes that create patterns in spatial data. In geographical information analysis, spatial statistics such as point pattern analysis, spatial autocorrelation, and spatial interpolation will analyze the spatial patterns, spatial processes, and spatial association that characterize spatial data. Understanding spatial analysis will help you realize what makes spatial data special and why spatial analysis reveals a truth about spatial data.

GeoInfo Map is a geospatial information service provided by the Hong Kong Special Administrative Region (HKSAR) Government to the general public, dedicated to facilitate the searching and understanding of geographical locations, the built and natural environments, and public facilities in Hong Kong. In GeoInfo Map, base map details and building information as well as the photo maps are provided by the Lands Department. Departmental and public facilities information is contributed by relevant Government departments while infrastructure and hosting of this website is provided by the Office of Government Chief Information Officer. Geospatial information underpins our daily activities. To cater public’s needs for convenient access to official digital map and geospatial information, LandsD developed this GeoInfo Map service for use by members of the general public. GeoInfo Map served as a common platform to foster sharing of geospatial information by enabling easy public access to the latest facility information released by government departments. Since the launch of the GeoInfo Map in May 2010, the LandsD has been working closely with 29 government departments for the delivery of up-to-date maps and geospatial information service for the public. Over the years, the content of the GeoInfo Map has enriched significantly from provision of 120 types of public facility geospatial information to 270. In order to enhance service quality, the Lands Department has recently conducted a large scale revamping exercise to improve the GeoInfo Map service. To facilitate web surfing with tablet computers and smartphones, responsive web design has been introduced in the revamped website which will detect and adapt to the device in use to deliver a smoother user experience. Apart from enhancing map browsing experience and performance, the new map interface enables users to search for various types of real-time information including weather, traffic, air and beach water quality. GeoInfo Map provides a powerful geographic search engine. It allows users to find any locations in Hong Kong by inputting address information, building names, community and public facility names, place names, road names, lot information, lamp post numbers, and GPS coordinates, etc. Users can also search for public facilities by different categories such as "Sports and Recreation", "Health", etc. GeoInfo Map also provides useful map tools such as drawing tools, share map tools, and drawing tools, etc. Using GeoInfo Map, users can use the navigation tool bar provided to view maps with different scales and level of details, and pan and zoom to any locations in Hong Kong. Apart from the topographic maps, users can have aerial views over the locations of Hong Kong with the Ortho Map function. LandsD is delighted to offer GeoInfo Map to the public. With integrated and comprehensive geospatial information, we hope the GeoInfo Map provides convenience and support to the general public. We would continuously improve the GeoInfo Map service quality. More geospatial information will be incorporated into GeoInfo Map in the future.

Sinkholes form through both natural and human-made processes. Most of us think about erosion on the surface of the earth, but erosion can occur in the subsurface as well. In fact, scientist and engineers have a very creative name for just such a process: internal erosion. If just the right factors come together in the subsurface, some very interesting things can occur, including sinkholes.

We normally build a dam to hold water back and store it for use in water supply, irrigation, hydropower, or flood control. But sometimes we have to let some water go. Whether we need it downstream or the impounded water behind the dam is simply too full to store any more, nearly every dam needs a spillway to safely discharge water. The spillway is a critical part of any dam and often the most complex component. So how does it work?

Untangling the various equipment you might see in an electrical substation. In many ways, the grid is a one-size-fits-all system - a gigantic machine to which we all connect spinning in perfect synchrony across, in some cases, an entire continent. On the other hand, our electricity needs, including when we need it, how much we need, and how reliably it should be delivered vary widely. Substations play a critical role in controlling and protecting the power grid.

Traffic management in dense urban areas is an extremely complex problem with a host of conflicting goals and challenges. One of the most fundamental of those challenges happens at an intersection, where multiple streams of traffic - including vehicles, bikes and pedestrians - need to safely, and with any luck, efficiently, cross each others’ paths. However we accommodate it now or in future, traffic will continue to be one of the biggest challenges in our urban areas and traffic signals will continue to be one of its solutions.

This video gives a quick description and demo of this ingenious pump. A hydraulic ram is a clever device invented over 200 years ago that can pump water uphill with no other external source of power except for the water flowing into it and there is a way to take advantage of this normally inauspicious effect for a beneficial use. The ram pump is an ingenious way to take advantage of the properties of fluids. We all need water for a variety of reasons, so being able to move it where we need it without any fancy equipment or external sources of power is a pretty nice tool to have in your toolbox.
