GIS question: visualisation of locations based on longitude/latitude

Hi,
First of all: I'm a total beginner for everything related to GIS. I'm a bit lost at where to start, so any hints are welcome.
I have a table with a number of locations, for each location I have values for the longitude and latitude (Oracle format).
Would it be able to visualize these locations on a map using Oracle Locator, MapViewer or Google Earth ? I'm using Oracle 10g with patch set 10.2.0.4.
Thanks,
Matthias

Oracle Database are having through Oracle Locator support for spatial data storage via its datatype sdo_geometry.
A good place to start is the user documentation:
http://download.oracle.com/docs/html/B14255_01/toc.htm
In your particular case your Longitude latitude columns could be use as follows:
Add a column GEOMETRY of datatype sdo_geometry to your table
UPdate that via:
update YOUR_TABLE a
set geometry=
sdo_geometry(
2001, ---2D point
8307, --- SRID (assuming WGS84 for your lon/lat)
sdo_point_type(a.longitude, b.latitude, null), ---specific point notation
null,
null);
create an entry in the user_sdo_geom_metadata (see user manual)
create an index (see user manual)
Once you have these in place, you can start looking to some solutions as you mentioned or as described by Ivan to use this data to be visualised.
Hoping this gives you a an idea where and how to start

Location based wifi

Hi!
Am I just a thick **bleep** or is it selfexplanatory how to use location based wifi?
Are you meant to have the Wi-Fi button ON or OFF when you're using location based wifi or is it meant to go on automatically when you are in the range of a certain wifi router? It states that it should "switch it on" whenever a configured network is within range but it doesn't.
If it is meant to go on automatically when you are within in range of a certain network, how did it get there in the first place? Yes, I know, stupid question. You have to switch Wi-Fi on initially and tell the Z2 that this is a network that I want you to connect to.
Anyway, perhaps some wizard can share some thoughts on this one...
Regards
Solved!
Go to Solution.

Leave it ON when using Wi-Fi and forget when going out.. the system will turn it OFF automatically.
If you wanna go back to Wi-Fi You need to turn the screen ON, cause Stamina mode is blocking any network operations.
Unlock it for 3 - 5 sec till the wi-fi logo apears and you good to go.

Is it possible to have location based CDR and QoE in Lync 2013

Hi,
Is it possible to have location based recording for CDR and QoE on monitoring database?

Possible? Yes. But you'll want to write your own report for it as what's native likely won't help you much. Check out the user activity report, search for a user and drill into the detail on that call. That takes you to the Peer to
Peer Session Detail report for that call, if you expand Media Quality report, you can see the IPs on each end, the location as defined in Lync, the client types... You'll just need to compile it into your own report for better readability.
We do that as part of our Lync managed services offering, we have custom reports that outline call quality issues per subnet so you can see how the call quality of a particular branch or wifi VLAN compares to another.

Siri keeps telling me "your calendar does not support location-based reminders" when I ask her to remind me to feed the cat when I get home. My address is in contacts and it has worked previously. Did iOS 8 change something?

calendar does not support location-based reminders....
i Just found a similar question below and it resolved my issue. Turn off the sync to exchange email and all works fine now.

Couldn't agree more. I've been *trying* to use location reminders ever since buying my iPhone 4S but as yet, out of many, many attempts they've only actually worked once.
The kid problem is very simple, the way the phone needs the location to be an address in your address book, and it's subsequent inability to correctly locate the address. My home address is a correct postal address, and has been unchanged for 40+ years, yet clicking on my address from my own contact entry puts my location some distance down my street.
Whilst I understand the issue with the address lookup, it seems to be a massive problem with the location based reminders as it's just not possible to set useful reminders.
What if I want to remind myself of something when I arrive at the car park on a shopping trip? There is no address for that in my contacts, I just want to pinpoint the location on the maps and say 'remind me when I get there'. Surely that's the simplest my far. Same with address book contacts, if you had a field with the gps position in then one could tag the locations and know they were 100% accurate for location services.
Such a shame as it's one of the key reasons I upgraded my phone and as it stands it just plain doesn't work.

Has Apple acknowledged that there's an issue with location based reminders?

After searching several posts, I haven't found where Apple is working on a solution for the location reminders issue. There are several recommendations that people make...but most don't seem to work. What say you Apple??
Please reply with a link if I missed something during my search that answers my question. Thx

It was a bug. In iOS 7.1 Apple fixed the location based Reminders. Users no longer need to have the Reminders app running in the background for location based reminders to fire off.

Devices and I are in one city but time zone and location based apps show devices location in another city

iPad2 with IOS 8.1.2 located with me in Eastern Time Zone city but settings under General reflects Central Time Zone(Chicago). All location based Apps are reflecting a Central Time Zone city, one that I have never visited. I did an erase and restore of a backup prior to this issue but it was not resolved. What do I do?

I am having a similar issue. I moved about 10-15 miles. Any app, such as Maps, a Weather, etc, that use location keep showing my current location as my old address. I'm interested in hearing the solution to your problem.

I set up a location based reminder in notification last week to test it out. Worked great, but now I cannot get rid of it. It does not show up in any list on the notifications pages, but can be found in search. How can I get rid of this notification?

Last week I set up a location based reminder in notifications to test it out. Worked great. However, I can't get rid of it. It does not show up on any of the pages, either reminders or completed. I can search and find it, shows it should be in reminders page, but it is not there for me to remove. Any ideas?

How to send location based push notification

How to send notification from website to the devices in particular latitude and longitude

I assume you mean you want the backend to send push notifications to a group of devices based on their geographical location?
In that case each device needs to register at startup with the notification service (Windows, Apple, Android, etc.), and get a handle, then register the information (along with its unique identification, such as account or phone number) with
Azure's notification hub. It also has to send its geographical location and the backend needs to keep this information somewhere (in a table, for example). The device needs to periodically update the backend for its new location. When the backend has the need
to send push notifications based on device's geographical location (based on a rectangular grid for example), then it has all the information to do it.

Location based reminders not working in IOS8 on iphone 5s, please help?

Location based reminders are not working when using Siri since upgrading to IOS8. Asking Siri to "remind me when I get home" also turns off reminders in Location Services. Please help

I have the same issue with Siri turning off the location setting for reminders. In fact my location based reminders do not work at all. IPhone 5s, ios 8.1, upgraded to 8.1.1 and that did not fix these issues.
SEems like Apple does not test the location setting every other upgrade to iOS. They break it, then fix it then break it etc...

Problems with location based applications

I am having problems with all of my location based applications i.e. none of them work. It seems I can never be located by the GPS no matter where i am and i just get a permanently spinning wheel. I have deleted and reloaded the Apps (although even with the generic Maps App i cannot be located) and i have reset the phone Reset iPhone (but havent Reset Settings or Restored yet). I love my iPhone but this is very frustrating. Can someone please help ?

Didn't work unfortunately. My Location Services were On so i proceeded to Restore. All went ok on the Restore but i still have the same problem. I have 4 App's that are location based and none of them work. Your suggestion ? Thanks for your help.

Location Based Security application?

Hello everyone,
I've been searching the App World for a 'Location Based' Security app, but can't seem to find what Im looking for.
I like the security that is native to the Blackberry, but when I am at work or at home, I like to not to have to use the password to access my device.
I am looking for something that would look at the location of the device and know whether or not the security should automatically be turned on.
Does anyone know if this has been developed?
Regards,
Dave

If you can change the settings via a script (or maybe a 3rd party product), you could update your AC profile to launch the script/program to either set or unset the configuration.
For example, I use a script (well, plain old batch file actually) to map network drives when a certain work profile is launched. There must be a way to set screen saver policy via a windows shell script (WSH)...

Location-based w/o having to make each item location-based?

Hi, I know how to make an entry on a reminder list location-based, but can you tell me how to set an entire reminder list to be location-based (if that's possible). In other words, can I make a reminder list called "Costco" and set it so that every item on the list (essentially the whole list) pops up when I enter the Costco store?
I have only been able to do this by setting each entry on the list as a location-based reminder, but I would like to set the entire list- and every item on it- to pop up when I enter that geo-fence.

Location based wifi not working as expected

I would expect that location based wifi would either turn wifi off if not in a place with saved networks, or turn wifi on if arriving in a place with saved networks, but it does neither. I have tested this by turning wifi on when at home, then periodically checking status in places with no networks saved or open, and it's still on, and also by turning wifi off when away from home, then checking at home to see if it's turned on, and it isn't. So doesn't seem to be working either way. I have stamina mode active, and some people have said that location based wifi won't work with this.but most say works just fine, and would have expected Sony to say if different power saving options were incompatible. Always have location sensing GPS turned on. Often have mobile data off. Some have said that this is necessary for location based wifi to work, but others not, and to my way of thinking, location based wifi should turn wifi off whenever out of range of saved network, and add long as phone has some way of knowing where it is to wake up wifi, then it shouldn't matter which location modality it uses. Can anyone shed any light on this? Google's not being very helpful. Thanks

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
You do need to have data turned on and as such you must also have Stamina mode turned off for this to work sorry.

Location based printing not working

Hello all,
I've been searching for an answer but coming up with nothing so I figured I'd give it a shot and ask. After installing a fresh version of Leopard (with the latest updates) on a computer and then copying the user data back onto said computer, the location based printing doesn't work anymore. The printers used to switch automatically, now they do not. They switched when going from one office (city) to the next. (I believe it used the different subnet addresses to tell where it was at on our network.)
Any ideas on how to "fix" it. All I see is that it's just supposed to work so there really isn't anything to fix.
Thanks in advance,
Eric

Hello Eric,
I am surprised to hear that you had this working. I use the Location function to switch between three different Ethernet connections (office, lab and training room) and I have never found that I can set a particular printer for the respective subnet.
As you know, you set your default printer in System Preferences > Print & Fax. I thought that if this was set to 'Last Printer Used' it would remember which printer was last used for the respective Location, but it always shows the last printer used regardless of which Location I selected.
FYI - I also have an alternate account which I use for home (also set as a Location for wireless connection). This is defaulted to a different printer compared to the work account, but is not influenced by the Location setting.
I would be interested to hear if anyone else has had this working.
